The addition is one of the basic operations of arithmetic, you can call it your best friend – just like your favourite cartoon characters. It is an action where two whole numbers are added together and the result is the total.
The speciality of addition is that many multiple digit numbers, can be added together to create a massive number.
Example :1+2 = 3
Example: 2+13 = 15
You can add in two ways horizontally or vertically (in materials).
