## Additive Identity (Whole Number Zero)

__Explanation :-__**Zero has an Additive Identity for Whole Numbers,** i.e. when Zero is added to any given whole number, the resultant number is always equal to the given whole number.
**In other words,** Zero does not affect any change in an addition expression.

Study the following examples :-

**Example 1 :-** 4 + 0 = 4

**Example 2 :-** 24 + 0 = 24

**Example 3 :-** 888 + 0 = 888

**Example 4 :-** 0 + 33 = 33

**Example 5 :-** 0 + 9 = 9

**Example 6 :-** 0 + 427 = 427

From the above examples you can learn that sum of Zero and any given whole number, always gives the result which is equal to the given whole number.
**So we can say, Zero has an additive Identity for Whole Numbers**
