2 + 3 = 3 + 2
Commutative Property of Addition
4 + (3 +7) = (4 + 3) + 7
Associative Property of Addition
23 x 1 = 23
Identity Property of Multiplication
a + b + c = c + b + a
Commutative Property of Addition

Identity Property of Addition
7 x (6 x a) = (7 x 6) x a
Associative Property of Multiplication
(6 x 7) x a = (7 x 6) x a
Commutative Property of Multiplication: NOTE: 7 and 6 are grouped in both expressions...Only the order changed
1 x 36 = 36
Identity Property of Multiplication
5 x 6 x 2 = 5 x 2 x 6
Commutative Property of Multiplication
3 + (8 + b) = 3 + (b + 8)
Commutative Property of Addition: NOTE: 8 and b are grouped in both expressions... Only the order changed
