Commutative Property of Addition:

A trick for the different properties:

- Associative Property always has parenthesis

- Commutative Property is always the same factor rearranged

0 = a × 0                      > Zero property

b × c = c × b                 > Commutative Property

(a × b) × c = a × (b × c) > Associative Property
