1. Identify the number property that justifies each equation.
a. (10a)58 = 58(10a)
b. 58(10a) = (58 • 10)a
c. x + 10 = 10 + x
d. 14 + (10 + x) = (14 + 10) + x
e. 23(n + 2) = 23n + 46
2. Using only numbers, and not letters, write your own equation that illustrates the
distributive property.
Your equation should show that you are “distributing” multiplication over addition
instead of adding what is inside the parentheses first.
