Math Vocab - Chapter 5

Question 1

Associative Property of Multiplication

Answer 1

The way numbers are grouped does not affect the product

(when using all multiplication operations)

(3 X 2) X 4 = 3 X (2 X 4)

Question 2

Commutative Property of Multiplication

Answer 2

The order in which numbers are multiplied does not affect the product

(when using all multiplication operations)

3 X 5 = 5 X 3

Question 3

Distributive Property

Answer 3

Multiply the addends of a number and then add those partial products

8 X 17 = (8 X 10) + (8 X 7)

Question 4

Partial Product

Answer 4

You find a part of the product when you decompose a multiplication problem

(using an area model or the distributitve property)

Add the partial products together to complete your answer

12 X 4 = (10 X 4) + (2 X 4)

= 40 + 8

= 48

Question 5

Operation

Answer 5

A mathematical process you use to find an answer.
