#estimation in maths

In math, addition is a crucial concept. It’s something we utilise on a daily basis. Let’s look at what it means to add or subtract integers. You have a total sum of two or more numbers when you add two or more numbers together. Sum is a method of combining items. The sum is a mathematical operation that joins two or more integers to form a new total. You’ll need to add two or more numbers whenever you use words like “all together,” “put together,” “how many in all,” “total,” and “sum.” When two objects are put together, the plus symbol (+) is used.
