area model

A model of multiplication that shows each place value product.

dividend

multiple

A product of a given whole number and any other whole number.

formula

A rule that is written as an equation.

factor pairs

A set of two whole numbers that, when multiplied, will result in a given product.

prime number

A whole number greater than 0 that has exactly two different factors, 1 and itself.

Associative Property of Multiplication

Changing the grouping of three or more factors does not change the product.

Commutative Property of Multiplication

Changing the order of the factors does not change the product.

Identity Property of Multiplication

If you multiply a number by one, the product is the same as that number.

inverse operations

Operations that undo each other.

remainder

The amount left over when one number is divided by another.

product

The answer to a multiplication problem.

area

The measure, in square units, of the inside of a plane figure

divide

To separate into equal groups and find the number in each group or the number of groups.

parentheses

Used in mathematics as grouping symbols for operations. When simplifying an expression, the operations within the parentheses are performed first.

Distributive Property

When one of the factors of a product is a sum, multiplying each addend before adding does not change the product.
