Unit 5 Vocabulary

• Associative property of multiplication – if three or more factors are multiplied, they can be grouped in any order, and the product will remain the same; a × b × c = (a × b) × c = a × (b × c)

• Commutative property of multiplication – if the order of the factors are changed, the product will remain the same; a × b = c; therefore, b × a = c

• Distributive property of multiplication – if multiplying a number by a sum of numbers, the product will be the same as multiplying the number by each addend and then adding the products together; a × (b + c) = (a × b) + (a × c)

Unit 6 Vocabulary

• Associative property of addition – if three or more addends are added, they can be grouped in any order, and the sum will remain the same; a + b + c = (a + b) + c = a + (b + c)

• Commutative property of addition – if the order of the addends are changed, the sum will remain the same; a + b = c; therefore, b + a = c

Multiple Choice

• Associative
