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.
