I can use a number line to graph and order real numbers. I can identify properties of and use operations with real numbers.

PropertyAdditionMultiplication Commutativea + b = b + aab = ba Associative(a+b) + c = a + (b+c)(ab)c = a(bc) Identity a + 0 = a 0 + a = a a ∙ 1 = a 1 ∙ a = a Inverse a + (-a) = 0 Distributive a(b + c) = ab + ac

Identify the property:  (3 + 9) + 8 = 3 + (9 + 8) ◦ Associative property of addition  14 ∙ 1 = 14 ◦ Identity property of multiplication
