PROPERTIES OF ADDITION
The order of which numbers are added does
 Commutative: not matter the answer is still the same
6+3+7=3+7+6

Associative: The order of the numbers is the same, the

Identity:
grouping has change but the answer is still the
same
(6 + 3) + 7 = 3 + (7 + 6)
Add any number to zero, the number stays the
same
7+ 0 = 7

