Question

How can addition properties help me add whole numbers

Answer 1

There are four addition properties that help to add whole numbers :

For any whole number a, b, and c ;

1. Closure property of addition -
`a+b`

For example:

2+3=5

4+3=7

We can conclude that if we add any two whole number , we get another whole number.

2. Associative property of addition- when any whole number or variable are added, then that can be grouped in different way without changing result

`a+(b+c)=(a+b)+c`

For example:

2+(3+4)=(2+3)+4

3. Commutative property of addition- when any whole number or variable are added, then the order changed without changing the result.

`a+b=b+a`

For example: 2+3=3+2

4. Identity property of addition- when 0 is added to a whole number or variable , the result is the same variable or number.

`a+0=0+a`

For example: 3+0=0+3

0 is called an Identity for addition of whole numbers.
