I need help on this!!

Answer:

Commutative

Step-by-step 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

$3 + b + 2 = 3 + 2 + b$
