Addition means combining together two or more quantities.
It is denoted by "+" symbol.
The numbers which get added are called addendends. The result of the addition is called "sum".
Things to remember:
1. If we add zero to any number the sum will be the number itself.
E.g. 5 + 0 = 5
2. If we add two numbers in any order their sum will always be same. This is known as cumulative property.
5 + 4 = 9 = 4 + 5
3. If we add 3 or more numbers their grouping will not matter. This is known as associative property. We should make groups to make our calculation easier.
7 + (5 + 8) = 20 = (7 + 5) + 8
