Properties of Real Numbers

Identify which property each of the following statements represents. Commutative Property 3 + (-8) = (-8) + 3 8 + 12 = 12 + 8 3 + (9 + 4) = 3 + (4 + 9) 2(7) = 7(2) Associative Property 3 + (9 + 4) = (3 + 9) + 4 9(8 • 2) = (9 • 8)2 Distributive Property 3(9 + 4) = 27 + 12 2(8 - 5) = 2(8) - 2(5) -5(7 + 2) = -5(7) + (-5)(2) Identity Property (-8) + 0 = -8 34 x 1 = 34 1 + 0 = 1 Inverse Property 9 + -9 = 0 18.23 + -18.23 = 0 5(1 = 1 1 x 4 = 1 Match the mathematical statement with the property it represents. 7( 1 ) = 7 Identity Property of Multiplication 2 + (3 + 8) = (2 + 3) + 8 Associative Property of Addition 7 + (-7) = 0 Inverse Property of Addition 7( 1 ) = 1 Inverse Property of Multiplication 7 + 0 = 7 Identity Property of Addition What property is being used from line 1 to line 2? 2 + 4 + 9 = 4 + 2 + 9 Associative Property of Addition Commutative Property of Addition Identity Property of Addition Inverse Property of Addition Distributive Property What property is being used from line 1 to line 2?2( 3 + 8)(2x3) + (2x8) Inverse Property Commutative Propery Distributive Property Associative Propery Identity Propery What property is being used from line 1 to line 2?(9 + 4) + 2 =9 + (4 + 2) Associative Property of Multiplication Commutative Property of Addition Commutative Property of Multiplication Distributive Property Associative Property of Addition
