• Use Commutative, Associative, and Identity properties to solve problems. • equivalent expressions • properties Identify Properties A. Name the property shown by the statement. 3 ● 10 ● 2 = 3 ● 2 ● 10 Answer: The order of the numbers changed. This is the Commutative Property of Multiplication. Identify Properties B. Name the property shown by the statement. (2 + 5) + m = 2 + (5 + m) Answer: The grouping of the numbers and variables changed. This is the Associative Property of Addition. A. Name the property shown by the statement. (4 ● 6) ● 2 = 4 ● (6 ● 2) A. Commutative Property of Multiplication B. Associative Property of Multiplication C. Multiplicative Identity D. Multiplicative Property of Zero A. B. C. D. A B C D B. Name the property shown by the statement. 12 + 9 = 9 + 12 A. Commutative Property of Addition B. Associative Property of Addition C. Additive Identity D. Distributive Property A. B. C. D. A B C D Identify Properties C. Name the property shown by the statement. r∙1=r Answer: The following statement is being multiplied by one, therefore the property being shown is the Multiplicative Identity. Identify Properties D. Name the property shown by the statement. 12 ∙ 0 = 0 Answer: The following statement is being multiplied by zero, therefore the property being shown is the Multiplicative Property of Zero. Identify Properties E. Name the property shown by the statement. k+0=k Answer: The following statement is being added by zero, therefore the property being shown is the Additive Identity. A.
