Question

A+9= Illustrate the commutative property of addition by finishing the statement

Answer 1

`a+9=9+a`

Explanation:

Let
`a,b\in \mathbb R` then the commutative property of addition states that:

`a+b=b+a`

This means that the order in which we add any two real numbers does not matter.

This implies that
`9+a` completes the given statement

`a+9=9+a`
