hi, so random post here: maths is actually wonderful.

Maths is absolutely everywhere. You really can’t escape it no matter where you go. It is the fundamental building block. Despite how math is taught in school, it is way different from the boring way it is taught in school. I don’t remember who said this, but there’s this quote: 

“The way maths is taught in school is like if an art class only taught their students how to paint fences.”

And you can see, only learning how to paint fences will make literally no one into an art person, so it goes the other way around too...

A number is divisible by:

2 - If it’s even (the last digit is even).

3 - If the sum of the number’s digits is divisible by 3.

4 - If you divide it by 2 and the quotient is even.

5 - If the final digit ends in 0 or 5.

6 - If it is divisible by both 2 and 3

7 - If (this one is trickier) you take the LAST digit of the number, multiply it by 2, then subtract it from the number formed by the remaining digits. Take the new number, and if it has more than one digit, repeat. Keep going until you have one digit. If that digit is 0 or 7, it is divisible by 7. Example: 259---> 25 - 2(9) = 25 - 18 = 7

8 - Keep dividing by 2
