Properties of Math Review

1. Match each equation with the correct property. (j + k) + m = ( k + j) + m commutative of addition e(fg) = (ef)g associative of multiplication w + (y + z) = (w + y) + z associative of addition 9(5 + 2) = 9(5) + 9(2) distributive 10 • 1 = 10 multiplicative identity s + 0 = s additive identity 2. x ( y + 3) = xy + 3x is an example of what property? Distributive Property Associative Property Commutative Property None 3. (4 • 5) • 6 = 4 • (5 • 6)is an example of what property? Distributive Property Associative Property Commutative Property None 4. 8 • 0 = 0 is an example of what property? Distributive Property Zero Property Commutative Property None 5. ☺ + ☯ = ☯ + ☺ is an example of what property? Distributive Property Associative Property Commutative Property None 6. Match the equations using the Associative Property. (6 • 1) • 2 = 6 • (1 • 2) (14 + 5) + 3 = 14 + (5 + 3) (7 • 5) • 11 = 7 • (5 • 11) 7. Identify which property each statement represents. Commutative -52 + 4 = 4 + (-52) 2(7) = 7(2) Distributive -5(7 + 2) = -5(7) + (-5)(2) 3(9 + 4) = 27 + 12 Inverse 23 + (-23) = 0 6 (1 = 1 Identity 13 + 0 = 13 1 (1) = 1
