1. Identify and label each of the mathematical properties below.
(Commutative, Associative, Identity, or Distributive)
a + b = b + a (a β’ b) β’ c = a β’ (b β’ c)
(a + b) + c = a + (b + c) a β’ b = b β’ a
n + 0 = n n Γ 1 = n
c(a + b) = ca +cb n Γ· 1 = n
n β 0 = n
2. Simplify each of the expressions below using any combination of the properties above and combining
like terms.
3x + 5 + 6x β 2(2 + 6x)
5(3x + 3) 3x + 5 β 6x + 16
