Python is a powerful and versatile programming language that can be used for various purposes, such as web development, data science, machine learning, automation, and more. One of the most popular applications of Python is data analysis, which involves processing, cleaning, manipulating, and visualizing data to gain insights and make decisions.

In this article, we will introduce some of the basic concepts and techniques of data analysis using Python, focusing on the data wrangling and analysis process. Data wrangling is the process of transforming raw data into a more suitable format for analysis, while data analysis is the process of applying statistical methods and tools to explore, summarize, and interpret data.

To perform data wrangling and analysis with Python, we will use two of the most widely used libraries: Pandas and NumPy. Pandas is a library that provides high-performance data structures and operations for manipulating tabular data, such as Series and DataFrame. NumPy is a library that provides fast and efficient numerical computations on multidimensional arrays, such as ndarray.

We will also use some other libraries that are useful for data analysis, such as Matplotlib and Seaborn for data visualization, SciPy for scientific computing, and Scikit-learn for machine learning.

To follow along with this article, you will need to have Python 3.6 or higher installed on your computer, as well as the libraries mentioned above. You can install them using pip or conda commands. You will also need a code editor or an interactive environment, such as Jupyter Notebook or Google Colab.

Let’s get started with some examples of data wrangling and analysis with Python.

Example 1: Analyzing COVID-19 Data

In this example, we will use Python to analyze the COVID-19 data from the World Health Organization (WHO). The data contains the daily situation reports of confirmed cases and deaths by country from January 21, 2020 to October 23, 2023. You can download the data from here.

First, we need to import the libraries that we will use:import pandas as pd import numpy as np import matplotlib.pyplot as plt import seaborn as sns

Next, we need to load the data into a Pandas DataFrame:df = pd.read_csv('WHO-COVID-19-global-data.csv')

We can use the head() method to see the first five rows of the DataFrame:df.head()

Date_reportedCountry_codeCountryWHO_regionNew_casesCumulative_casesNew_deathsCumulative_deaths2020–01–21AFAfghanistanEMRO00002020–01–22AFAfghanistanEMRO00002020–01–23AFAfghanistanEMRO00002020–01–24AFAfghanistanEMRO00002020–01–25AFAfghanistanEMRO0000

We can use the info() method to see some basic information about the DataFrame, such as the number of rows and columns, the data types of each column, and the memory usage:df.info()

Output:

RangeIndex: 163800 entries, 0 to 163799 Data columns (total 8 columns): # Column Non-Null Count Dtype — — — — — — — — — — — — — — — 0 Date_reported 163800 non-null object 1 Country_code 162900 non-null object 2 Country 163800 non-null object 3 WHO_region 163800 non-null object 4 New_cases 163800 non-null int64 5 Cumulative_cases 163800 non-null int64 6 New_deaths 163800 non-null int64 7 Cumulative_deaths 163800 non-null int64 dtypes: int64(4), object(4) memory usage: 10.0+ MB “><class 'pandas.core.frame.DataFrame'> RangeIndex: 163800 entries, 0 to 163799 Data columns (total 8 columns): # Column Non-Null Count Dtype --- ------ -------------- ----- 0 Date_reported 163800 non-null object 1 Country_code 162900 non-null object 2 Country 163800 non-null object 3 WHO_region 163800 non-null object 4 New_cases 163800 non-null int64 5 Cumulative_cases 163800 non-null int64 6 New_deaths 163800 non-null int64 7 Cumulative_deaths 163800 non-null int64 dtypes: int64(4), object(4) memory usage: 10.0+ MB

We can see that there are some missing values in the Country_code column. We can use the isnull() method to check which rows have missing values:df[df.Country_code.isnull()]

Output:

Date_reportedCountry_codeCountryWHO_regionNew_casesCumulative_casesNew_deathsCumulative_deaths2020–01–21NaNInternational conveyance (Diamond Princess)WPRO00002020–01–22NaNInternational conveyance (Diamond Princess)WPRO0000……………………2023–10–22NaNInternational conveyance (Diamond Princess)WPRO07120132023–10–23NaNInternational conveyance (Diamond Princess)WPRO0712013

We can see that the missing values are from the rows that correspond to the International conveyance (Diamond Princess), which is a cruise ship that had a COVID-19 outbreak in early 2020. Since this is not a country, we can either drop these rows or assign them a unique code, such as ‘IC’. For simplicity, we will drop these rows using the dropna() method:df = df.dropna()

We can also check the data types of each column using the dtypes attribute:df.dtypes

Output:Date_reported object Country_code object Country object WHO_region object New_cases int64 Cumulative_cases int64 New_deaths int64 Cumulative_deaths int64 dtype: object

We can see that the Date_reported column is of type object, which means it is stored as a string. However, we want to work with dates as a datetime type, which allows us to perform date-related operations and calculations. We can use the to_datetime() function to convert the column to a datetime type:df.Date_reported = pd.to_datetime(df.Date_reported)

We can also use the describe() method to get some summary statistics of the numerical columns, such as the mean, standard deviation, minimum, maximum, and quartiles:df.describe()

Output:

New_casesCumulative_casesNew_deathsCumulative_deathscount162900.000000162900.000000162900.000000162900.000000mean1138.300062116955.14016023.4867892647.346237std6631.825489665728.383017137.25601215435.833525min-32952.000000–32952.000000–1918.000000–1918.00000025%-1.000000–1.000000–1.000000–1.00000050%-1.000000–1.000000–1.000000–1.00000075%-1.000000–1.000000–1.000000–1.000000max -1 -1 -1 -1

We can see that there are some negative values in the New_cases, Cumulative_cases, New_deaths, and Cumulative_deaths columns, which are likely due to data errors or corrections. We can use the replace() method to replace these values with zero:df = df.replace(-1,0)

Now that we have cleaned and prepared the data, we can start to analyze it and answer some questions, such as:

Which countries have the highest number of cumulative cases and deaths?

How has the pandemic evolved over time in different regions and countries?

What is the current situation of the pandemic in India?

To answer these questions, we will use some of the methods and attributes of Pandas DataFrame, such as:

groupby() : This method allows us to group the data by one or more columns and apply aggregation functions, such as sum, mean, count, etc., to each group.

sort_values() : This method allows us to sort the data by one or more

loc[] : This attribute allows us to select a subset of the data by labels or conditions.

plot() : This method allows us to create various types of plots from the data, such as line, bar, pie, scatter, etc.

A web service is a software system that provides functionality over the web using HTTP protocols. It is essentially a remote procedure call (RPC) that is invoked by a client application. Web services are typically stateless and highly scalable.

PHP is a popular programming language that can be used to develop web services. It is a server-side language that is well-suited for developing dynamic and interactive web applications.

To develop a web service in PHP, you will need to:

Choose a web service framework. There are a number of PHP web service frameworks available, such as Laravel, Symfony, and Lumen. These frameworks provide a number of features that can help you to develop web services more efficiently, such as routing, authentication, and error handling.

Create a web service endpoint. A web service endpoint is the URL that clients will use to access your web service. You can create a web service endpoint by creating a new PHP file and defining a route for it in your web service framework.

Write the web service code. The web service code is the code that will be executed when a client calls the web service endpoint. This code will typically perform some kind of operation, such as retrieving data from a database or sending an email.

Return the results of the web service call. The results of the web service call can be returned in a variety of formats, such as JSON, XML, or HTML.

Here is a simple example of a PHP web service that returns a list of users:

PHP<?php // Require the Laravel web service framework require 'vendor/autoload.php'; // Define the web service route Route::get('/users', function() { // Get the list of users from the database $users = DB::table('users')->get(); // Return the list of users in JSON format return response()->json($users); });

To call this web service, you would simply make a GET request to the following URL:http://localhost/users

The web service would then return a JSON response containing a list of all of the users in the database.

PHP web services can be used to develop a wide variety of applications, such as:

REST APIs

SOAP APIs

XML-RPC APIs

JSON-RPC APIs

PHP is a server-side scripting language that is commonly used to create dynamic websites. It is a popular choice for web development because it is easy to learn and use, and it is free and open-source.

To create a dynamic website with PHP, you will need to:

Install PHP on your web server.

Create a database to store your dynamic content.

Write PHP code to interact with the database and generate dynamic HTML pages.

Here is a simple example of how to use PHP to create a dynamic website:

PHP<?php // Connect to the database. $db = new PDO('mysql:host=localhost;dbname=my_database', 'root', ''); // Get the current date and time. $date = date('Y-m-d'); $time = date('H:i:s'); // Get the latest news articles from the database. $sql = 'SELECT * FROM news_articles ORDER BY published_at DESC'; $result = $db->query($sql); // Start generating the HTML for the web page. ?> <!DOCTYPE html> <html> <head> <title>My Dynamic Website</title> </head> <body> <h1>My Dynamic Website</h1> <h2>Latest News Articles</h2> <ul> <?php foreach ($result as $article): ?> <li> <h3><a href="<?php echo $article['url']; ?>"><?php echo $article['title']; ?></a></h3> <p><?php echo $article['excerpt']; ?></p> <p>Published on <?php echo $article['published_at']; ?></p> </li> <?php endforeach; ?> </ul> <h2>Current Date and Time</h2> <p>The current date and time is: <?php echo $date . ' ' . $time; ?></p> </body> </html> <?php // Close the database connection. $db = null; ?>

This code will connect to the database, get the latest news articles, and generate a dynamic HTML web page with the list of articles and the current date and time.

You can use PHP to create all sorts of dynamic websites, from simple blogs and news websites to complex e-commerce websites and social networking platforms.

Here are some tips for creating dynamic websites with PHP:

Use a database to store your dynamic content. This will make it easier to manage and update your content.

Use PHP functions to interact with the database and generate dynamic HTML pages.

Use PHP sessions to track user activity and preferences.

Use PHP cookies to store user data on the user's computer.

Use PHP security features to protect your website from attacks.

Bilingual and multilingual classrooms are settings where students and teachers use more than one language for communication and learning. Bilingual and multilingual classrooms can have different models and goals, such as dual language, bilingual, or translanguaging programs. In these classrooms, students can benefit from learning phonics in both their home language and English, as well as transferring their phonics knowledge across languages.

Here are some benefits and challenges of using phonics in bilingual and multilingual classrooms, as well as some strategies and resources for teachers.

Benefits of Using Phonics in Bilingual and Multilingual Classrooms

Phonics can help students develop phonemic awareness, which is the ability to hear, identify, and manipulate the individual sounds in spoken words. Phonemic awareness is a crucial skill for reading, as it allows students to apply their knowledge of phonics to decode unfamiliar words. Phonemic awareness can be developed in any language, and it can transfer across languages that share similar sounds.

Phonics can help students learn the alphabetic principle, which is the understanding that letters represent sounds in written words. The alphabetic principle can also be learned in any language, and it can transfer across languages that use the same or similar writing systems. For example, students who learn the letter-sound correspondences in Spanish can use them to read and write English words that have the same or similar spellings, such as cat/gato or sun/sol.

Phonics can help students develop vocabulary and comprehension skills in both languages. Vocabulary is the set of words that a person knows and uses. Comprehension is the ability to understand and interpret what they read. Vocabulary and comprehension depend on both decoding skills (using phonics) and linguistic skills (using grammar and meaning). By learning phonics in both languages, students can access more words and texts in each language, as well as make connections between languages.

Challenges of Using Phonics in Bilingual and Multilingual Classrooms

Phonics can be challenging for students who speak languages that have different sounds or writing systems from English. For example, students who speak Mandarin Chinese may have difficulty with some English sounds that do not exist in their language, such as /th/ or /r/. Students who speak Arabic may have difficulty with some English letters that do not exist in their writing system, such as p or v. Teachers need to be aware of these differences and provide explicit instruction and practice for students to master them.

Phonics can be challenging for students who speak languages that have different spelling rules or patterns from English. For example, students who speak French may have difficulty with some English spellings that do not follow the same rules or patterns as their language, such as silent letters (e.g., knife) or irregular spellings (e.g., said). Teachers need to be aware of these differences and provide explicit instruction and practice for students to learn them.

Phonics can be challenging for teachers who need to balance the use of two or more languages in their instruction. Teachers need to be strategic in their use of the languages, such as choosing which language to use for which purpose, when to switch languages, and how to scaffold students’ learning in each language. Teachers also need to coordinate their instruction across languages, such as aligning the phonics skills and content that they teach in each language.

Strategies and Resources for Using Phonics in Bilingual and Multilingual Classrooms

Teachers can use a systematic and explicit approach to teach phonics in both languages. A systematic approach means that teachers follow a logical sequence of phonics skills from simple to complex, such as starting with short vowels and consonants and moving on to long vowels and consonant blends. An explicit approach means that teachers teach each phonics skill directly and clearly, such as explaining the sound-spelling relationship, modeling how to read and write words with that skill, and providing guided practice and feedback.

Teachers can use a cross-linguistic approach to teach phonics across languages. A cross-linguistic approach means that teachers make connections between the languages that students speak and learn, such as highlighting the similarities and differences between the sounds and spellings of words in each language, using cognates (words that have the same or similar meaning and form across languages) to build vocabulary and comprehension, and using translanguaging (the flexible use of multiple languages) to support communication and learning.

Teachers can use a variety of activities and materials to teach phonics in both languages. Some examples of activities and materials are:

Sound boxes: a visual tool that helps students segment and blend sounds in words. They consist of a long rectangle divided into squares that represent the number of sounds in a word. For example, the word cat has three sounds and three boxes: /k/ /a/ /t/. To use sound boxes for phonics, write the word on a board or a card and draw the corresponding sound boxes below it. Then, ask students to say each sound in the word as they point to each box. Next, ask them to write each letter or letter combination that makes each sound in each box. Finally, ask them to say the whole word as they slide their finger under the boxes.

Flashcards: a simple and effective way to review phonics skills with students. They can be used for individual or group practice, as well as for games and activities. To make flashcards for phonics, write each word or letter-sound correspondence on a card or use pre-made cards from online sources. To use flashcards for phonics, show each card to a student or a group of students and ask them to read the word or say the sound aloud. If they read it correctly, praise them and move on to the next card. If they read it incorrectly or hesitate for more than three seconds, tell them the correct word or sound and ask them to repeat it. Then put the card aside and review it again later.

Books or texts: a rich and authentic way to expose students to phonics skills in both languages. Teachers can select books or texts that contain words with the phonics skills that they are teaching, such as short vowels, long vowels, consonant blends, etc. Teachers can also select books or texts that are bilingual or multilingual, such as books that have the same story in two languages or texts that mix languages. Teachers can use books or texts for phonics instruction by:

Reading aloud: reading the book or text aloud to students and drawing their attention to the words with the phonics skills that they are learning, such as asking them to identify the sounds or spellings of those words.

Shared reading: reading the book or text together with students and inviting them to join in reading the words with the phonics skills that they are learning, such as asking them to point to those words or read them aloud.

Independent reading: allowing students to read the book or text on their own or with a partner and encouraging them to practice the phonics skills that they are learning, such as asking them to find those words or write them down.

Using phonics in bilingual and multilingual classrooms can help students develop their reading and writing skills in both their home language and English, as well as enhance their bilingualism and multilingualism. Phonics is not only a skill, but also a resource that students can use to access more languages and literacies.

Phonics is a method of teaching reading that focuses on the relationship between letters and sounds. Phonics helps children learn to decode words by breaking them down into their smallest units of sound, called phonemes, and matching them with the corresponding letters or letter combinations, called graphemes.

Phonics can be fun and engaging for children if they are taught with creative and interactive activities that appeal to their senses, interests, and learning styles. Here are some examples of phonics activities that you can try with your children at home or in the classroom:

Sound Bingo: This is a game that helps children practice identifying and matching sounds with letters. You will need a set of bingo cards with different letters or letter combinations on them, and a set of cards or tokens with pictures of words that start or end with those letters or letter combinations. You can also use an online tool to generate the bingo cards and the tokens. To play the game, you will call out a word from the tokens, such as “cat”, and the children will have to find the letter or letter combination that makes the sound /k/ on their bingo cards, such as “c” or “k”. The first child to complete a row, column, or diagonal on their bingo card wins the game.

Phonics Hopscotch: This is a game that helps children practice blending sounds to read words. You will need a chalk or tape to draw a hopscotch grid on the floor, and some cards with words that are made up of two or three phonemes, such as “dog”, “sun”, or “fish”. You can also use an online tool to generate the words. To play the game, you will place a card with a word on each square of the hopscotch grid. The children will have to hop on each square and say the sounds and then the word as they land on it. For example, if they land on “dog”, they will say /d/, /o/, /g/, “dog”. You can make the game more challenging by using words with more phonemes or silent letters, such as “star”, “jump”, or “knight”.

Phonics Treasure Hunt: This is a game that helps children practice segmenting sounds to spell words. You will need some small objects that represent words that are made up of two or three phonemes, such as a toy car, a hat, or a ring. You will also need some paper cups or boxes to hide the objects in, and some stickers or labels to write the letters or letter combinations that make up the sounds in the words. You can also use an online tool to generate the stickers or labels. To play the game, you will hide the objects in different locations around the room, and stick the labels on the cups or boxes that contain them. The children will have to find the objects and say the word and then the sounds as they open the cups or boxes. For example, if they find a toy car, they will say “car”, /k/, /a/, /r/. You can make the game more challenging by using objects that represent words with more phonemes or silent letters, such as a star, a comb, or a knife.

Phonics is a method of teaching reading that focuses on the relationship between letters and sounds. Phonics helps children learn to decode words by breaking them down into their smallest units of sound, called phonemes, and matching them with the corresponding letters or letter combinations, called graphemes.

Phonics instruction has many benefits for children of all ages and abilities, especially for those who are learning English as a second language or who have reading difficulties. Some of the benefits of phonics instruction are:

It improves children’s reading accuracy and fluency. Phonics instruction teaches children how to sound out words and read them correctly. This helps children read faster and more smoothly, which enhances their comprehension and enjoyment of reading.

It improves children’s spelling and writing skills. Phonics instruction teaches children how to segment words into phonemes and write them with the correct graphemes. This helps children spell words correctly and express their ideas in writing.

It improves children’s vocabulary and language skills. Phonics instruction exposes children to a variety of words and texts, which enriches their vocabulary and language development. It also helps children learn the rules and patterns of English, such as prefixes, suffixes, and word families, which enhance their language skills.

It improves children’s confidence and motivation. Phonics instruction gives children a clear and systematic way to learn how to read, which boosts their confidence and self-esteem. It also makes reading more fun and engaging, which motivates children to read more and improve their skills.

Phonics instruction can be delivered in different ways, such as synthetic, analytic, analogy, or embedded phonics. Each method has its own advantages and disadvantages, and the most effective one depends on the individual needs and abilities of the students. Teachers should assess their students’ strengths and weaknesses and adapt their instruction accordingly.

Phonics instruction is an essential component of a balanced and comprehensive literacy program that includes other reading skills, such as comprehension, vocabulary, and fluency. By providing phonics instruction to their students, teachers can help them become confident and competent readers who can enjoy the wonders of written language.

Phonics is a method of teaching reading that focuses on the relationship between letters and sounds. Phonics helps children learn to decode words by breaking them down into their smallest units of sound, called phonemes, and matching them with the corresponding letters or letter combinations, called graphemes.

There are different ways to teach phonics, and each one has its own advantages and disadvantages. In this article, we will explore four of the most common phonics teaching methods: synthetic, analytic, analogy, and embedded.

Synthetic Phonics Synthetic phonics is a type of phonics instruction that teaches children to identify and pronounce all the phonemes in a word, and then blend them together to read the word. For example, to read the word “ship”, children would first say the sounds /sh/, /i/, and /p/, and then blend them together to say “ship”.

Synthetic phonics is considered to be the most direct and systematic way of teaching phonics. It starts with teaching the basic single-letter phonemes (such as /a/, /b/, /c/, etc.) and then progresses to more complex multi-letter phonemes (such as /sh/, /ch/, /th/, etc.). Synthetic phonics also teaches children to segment words into phonemes when spelling. For example, to spell the word “ship”, children would first say the word and then break it down into the sounds /sh/, /i/, and /p/, and write the letters “s”, “h”, “i”, and “p”.

Synthetic phonics has been shown by research to be the most effective method of teaching reading, especially for young children and struggling readers. It provides a clear and structured approach that helps children master the code of written language. It also helps children develop phonemic awareness, which is the ability to hear and manipulate individual sounds in words.

Some of the advantages of synthetic phonics are:

It is easy to follow and implement It covers all the phonemes and graphemes in the English language It helps children read unfamiliar words by applying their knowledge of phonics It improves children’s spelling skills by teaching them to segment words into phonemes Some of the disadvantages of synthetic phonics are:

It can be boring and repetitive for some children It can neglect other aspects of reading, such as comprehension, vocabulary, and fluency It can be confusing for some children who speak dialects or languages that have different pronunciations or spellings than standard English Analytic Phonics Analytic phonics is a type of phonics instruction that teaches children to analyze whole words and identify common patterns or chunks within them. For example, to read the word “ship”, children would first recognize the word as a whole and then notice that it contains the chunk “-ip”, which they have already learned in other words, such as “lip” or “tip”.

Analytic phonics is considered to be a more indirect and holistic way of teaching phonics. It starts with teaching high-frequency words that are easy to recognize and remember, such as “the”, “and”, “is”, etc. Then it introduces new words that share similar patterns or chunks with the known words, such as “this”, “sand”, “his”, etc. Analytic phonics also teaches children to use context clues and pictures to help them read words.

Analytic phonics has been shown by research to be effective for some children who have good visual memory and can easily recognize words by sight. It also helps children develop word recognition skills, which are essential for reading fluency and comprehension.

Some of the advantages of analytic phonics are:

It is more interesting and meaningful for some children It exposes children to a variety of words and texts It helps children read words that do not follow regular phonics rules, such as “one” or “said” It enhances children’s comprehension skills by teaching them to use context clues and pictures Some of the disadvantages of analytic phonics are:

It can be inconsistent and confusing for some children It does not cover all the phonemes and graphemes in the English language It does not help children read unfamiliar words that do not have common patterns or chunks It does not improve children’s spelling skills by teaching them to segment words into phonemes Analogy Phonics Analogy phonics is a type of phonics instruction that teaches children to use known words as analogies to read new words. For example, to read the word “ship”, children would first think of a word that they know that has the same ending sound, such as “lip”. Then they would replace the beginning sound with the new one, such as /sh/, to form the new word “ship”.

Analogy phonics is considered to be a combination of synthetic and analytic phonics. It uses both the blending and the chunking strategies to help children read words. It also teaches children to use word families, which are groups of words that share the same rime (the part of a word that follows the first consonant or consonant cluster), such as “-at”, “-ip”, “-op”, etc.

Analogy phonics has been shown by research to be effective for some children who have good phonemic awareness and can easily manipulate sounds in words. It also helps children develop word analysis skills, which are useful for reading and spelling.

Some of the advantages of analogy phonics are:

It is more flexible and creative for some children It builds on children’s existing knowledge of words It helps children read words that have irregular spellings, such as “yacht” or “rough” It supports children’s spelling skills by teaching them to use word families Some of the disadvantages of analogy phonics are:

It can be challenging and confusing for some children It does not teach all the phonemes and graphemes in the English language It does not help children read words that do not belong to any word family, such as “the” or “was” It requires children to have a good vocabulary and memory of words Embedded Phonics Embedded phonics is a type of phonics instruction that teaches children to use phonics skills within the context of meaningful texts. For example, to read the word “ship”, children would encounter it in a sentence or a story that makes sense and provides clues for its meaning and pronunciation.

Embedded phonics is considered to be a more incidental and integrated way of teaching phonics. It does not follow a specific sequence or scope of phonics skills, but rather covers them as they appear in texts. It also does not teach phonics skills in isolation, but rather in connection with other reading skills, such as comprehension, vocabulary, and fluency.

Embedded phonics has been shown by research to be effective for some children who have good oral language skills and can easily infer meaning from texts. It also helps children develop reading comprehension skills, which are the ultimate goal of reading.

Some of the advantages of embedded phonics are:

It is more natural and authentic for some children It motivates children to read for meaning and enjoyment It helps children read words that have multiple meanings or pronunciations, such as “wind” or “read” It fosters children’s love of reading and literature Some of the disadvantages of embedded phonics are:

What is mental arithmetic?

Mental arithmetic is the ability to perform calculations in one’s mind without using any external aids such as paper, pencil, or calculator. Mental arithmetic can improve one’s memory, concentration, logical thinking, and creativity. It can also enhance one’s speed and accuracy in solving mathematical problems.

How does the abacus help in mental arithmetic?

The abacus helps in mental arithmetic by providing a visual and tactile representation of numbers and operations. By manipulating the beads on the abacus, one can learn the basic principles of arithmetic and number sense. The abacus also helps in developing a mental image of the beads and their positions, which can be used to perform calculations mentally.

The abacus system of mental calculation is a system where users mentally visualize an abacus to carry out arithmetical calculations. No physical abacus is used; only the answers are written down. Calculations can be made at great speed in this way.

The abacus has several advantages over using the modern calculator for mental arithmetic. The main advantage is the ability to perform arithmetic operations mentally as the calculations are performed with two hands, improving the work of both hemispheres of the brain. Activation of the two hemispheres of the brain leads to the formation of neural connections.

How to learn mental arithmetic using the abacus?

To learn mental arithmetic using the abacus, one needs to follow these steps:

Learn how to use the abacus to represent numbers and perform basic operations such as addition, subtraction, multiplication, and division. Each rod on the abacus represents a place value, such as ones, tens, hundreds, etc. The rods are arranged from right to left, with the ones place being the farthest right. Each bead on the abacus has a value depending on its position and the rod it is on. The beads on the upper part of the rod are called heaven beads and have a value of 5. The beads on the lower part of the rod are called earth beads and have a value of 1. To represent a number on the abacus, one needs to move the beads towards the center beam. To reset the abacus to zero, one needs to move all the beads away from the center beam.

Practice using the abacus regularly and master different techniques and methods for each operation. For example, to add two numbers, one needs to align them on the same place value and then add each pair of beads from right to left. To subtract two numbers, one needs to align them on the same place value and then subtract each pair of beads from right to left. To multiply two numbers, one needs to use repeated addition or a multiplication table. To divide two numbers, one needs to use repeated subtraction or a division table.

Gradually transition from using the physical abacus to using a mental image of the abacus. This can be done by reducing the size of the abacus, hiding some parts of it, or closing one’s eyes while using it. The goal is to visualize the beads moving on the abacus as one performs each operation mentally.

Challenge oneself with more complex and varied problems that require mental arithmetic skills. For example, one can try solving problems involving fractions, decimals, percentages, algebra, geometry, etc.

Vedic mathematics has its roots in the Vedic age, which is estimated to be between 1500 BCE and 600 BCE. During this period, the ancient Indian sages composed the four Vedas, which are the oldest and most sacred texts of Hinduism. The Vedas contain various branches of knowledge, such as philosophy, spirituality, astronomy, medicine, and mathematics. The mathematical concepts and principles that are found in the Vedas are called Vedic mathematics.

Vedic mathematics is not only a collection of methods or techniques to perform calculations faster and easier, but also a way of understanding the nature of numbers and their relationships. Vedic mathematics reveals the harmony and beauty of mathematics and shows how it is connected to other fields of knowledge. Vedic mathematics also reflects the ancient Indian worldview, which is based on the concept of unity in diversity. According to this concept, everything in the universe is interconnected and interdependent, and can be expressed by numbers and patterns.

Vedic mathematics has many applications and advantages in the modern world. It can help students to improve their mental abilities, such as memory, concentration, creativity, and logical thinking. It can also make mathematics more enjoyable and interesting for learners of all ages and levels. Moreover, Vedic mathematics can be useful for solving problems in various domains, such as science, technology, engineering, art, and music.

Vedic mathematics has many applications and advantages in modern science and technology. Some of the benefits of Vedic mathematics are:

It makes calculations faster and easier by using mental math techniques.

It reduces the chances of errors and mistakes by simplifying the steps.

It enhances the creativity and logical thinking of the learners by offering multiple ways to solve the same problem.

It increases the interest and confidence of the learners in mathematics by making it fun and enjoyable.

Some of the examples of how Vedic mathematics is compatible with modern science are:

Physics: The concepts of atoms, molecules and substances can be traced back to the Vedic age. Moreover, the concepts of astronomy, metaphysics and spirituality are described in the Rig Veda, the ancient Hindu scriptures of the Vedic period3. The German physicist Werner Heisenberg once said: "About Indian philosophy, some of the ideas of quantum physics that seemed so crazy suddenly became more meaningful".

Computer Science: The Vedic math algorithms have become the leader in solving technology-related problems in the present digital and computer age. Many researchers working at top-level science and technology organizations like NASA, Intel, SPIE, and IEEE have used Vedic math concepts and presented them in various research papers.

Engineering: The fundamental concept of Vedic Mathematics lies in the natural principles on which the human mind works and is very much interesting for large-scale computations. This is precisely what makes it more relevant in case of some useful use of Computer Science together with Electronics and Communication Engineering.

Vedic mathematics is a system of mathematics that was discovered by an Indian mathematician, Jagadguru Shri Bharati Krishna Tirthaji, from the ancient Hindu scriptures called the Vedas. He published his findings in a book titled Vedic Mathematics in 19651. Vedic mathematics is based on 16 formulas (sutras) and 13 sub-formulas (sub-sutras) that can be used to solve various problems in arithmetic, algebra, geometry, calculus, and more2. Some of the benefits of Vedic mathematics are:

It makes calculations faster and easier by using mental math techniques.

It reduces the chances of errors and mistakes by simplifying the steps.

It enhances the creativity and logical thinking of the learners by offering multiple ways to solve the same problem.

It increases the interest and confidence of the learners in mathematics by making it fun and enjoyable.

Some of the examples of Vedic mathematics sutras are:

Ekadhikena Purvena: By one more than the previous one. This sutra can be used to find squares of numbers ending with 5. For example, to find the square of 25, we add one to the first digit (2+1=3) and multiply it with the first digit (3×2=6). Then we append 25 to the result. So, 25^2 = 625.

Nikhilam Navatashcaramam Dashatah: All from 9 and the last from 10. This sutra can be used to subtract a number from a power of 10. For example, to subtract 456 from 1000, we subtract each digit of 456 from 9, except the last one, which we subtract from 10. So, 1000 - 456 = (9-4)(9-5)(10-6) = 544.

Urdhva Tiryagbhyam: Vertically and crosswise. This sutra can be used to multiply two numbers of any length. For example, to multiply 23 by 14, we multiply the digits vertically and crosswise and add them. So, 23 × 14 = (2×1)(2×4+3×1)(3×4) = (2)(11)(12) = 322.
