**Addition**

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**
