1. 7) Properties
LT# 1E

2. Commutative Property Addition and Multiplication are commutative
Commute = move around
Commutative Property
Addition and Multiplication are commutative
Changing the order does not change the result
5 + 3 = 3 + 5
(6)(7)(2) = (7)(2)(6)

3. Associative Property Addition and Multiplication are associative
Grouping does not change the result
(6 + 3) + 7 = 6 + (3 + 7)
5(14 · 2) = (5 · 14)(2)

4. Identity Properties Answer stays the same
Identity = identical
Identity Properties
Answer stays the same
Zero is the additive identity
6 + 0 = 6 x + 0 = x
One is the multiplicative identity
2 (1) = 2 a (1) = a

5. Distributive Property
“to share”
5 (x + y) = 5x + 5y
6 (15) = 6(10) + 6(5)
10 (2 – 6) = 10(2) – 10(6)

6. Inverse Properties “undoes” the operation Additive Inverse: 6 + -6 = 0
Multiplicative Inverse: 6 · = 1
