Question

I need help on this!!

Answer 1

Commutative

Explanation:

Given

`3 + b + 2 = 3 + 2 + b`

Required

What law is applied

The applied law is commutative law of addition.

This law states that:

`a + b = b + a`

So:

`3 + b + 2 = 3 + (b + 2)`

When the positions of 2 and b are interchanged, we have:

`3 + b + 2 = 3 + (2 + b)`

Remove bracket

`3 + b + 2 = 3 + 2 + b`
