1
Properties of Addition and Multiplication

2
Distributive Property A(B + C) = AB + BC 4(3 + 5) = 4x3 + 4x5

3
Commutative Property of addition and multiplication Order doesn’t matter A x B = B x A A + B = B + A

4
Associative Property of multiplication and Addition Associative Property (a · b) · c = a · (b · c) Example: (6 · 4) · 3 = 6 · (4 · 3) Associative Property (a + b) + c = a + (b + c) Example: (6 + 4) + 3 = 6 + (4 + 3)

5
Identity Properties Additive Identity--If you add 0 to any number, the number stays the same. A + 0 = A or 5 + 0 = 5 Multiplicative Identity--If you multiply any number times 1, the number stays the same. A x 1 = A or 5 x 1 = 5
