A number that is multiplied by another number to find a product.

Terms that have identical variable parts that are raised to the identical power. Example: 5x² and 2x²

A number multiplied by a variable in an algebraic expression. Example: The 7 in 7g

The answer to an addition problem.

To find the VALUE of an expression by following the order of operations (PEMDAS)

The answer to a subtraction problem.

Combining like terms to make an algebraic expression in its smallest form. Example: 5x + 2x = 7x

Tells the order to solve steps in an expression that has more than one operation (PEMDAS)

A letter that represents an unknown value. Example: y

A whole number greater than 1 with only 2 factors; one and itself. Example: 7

Expressions that always have the same value. Example: 4x + 2x + 5 and 6x + 5

A whole number greater than 1 with more than 2 factors; opposite of prime. Example: 15 has 4 factors: 1, 3, 5, 15

The number that is going to be raised to a power. Example: 8^{4 The 8 is the what?}

Each part of an expression that is separated by addition or subtraction signs. Example: 5r + 7d - 8 has 3 of these

The answer to a multiplication problem.

An expression that consists of variables, numbers and operation symbols. Example: 4 + a

The least multiple, not including 0, shared by 2 or more whole numbers. Example: 4 and 6 The _____ is 12

The property in that says changing the grouping of numbers will not change the value. Ex: (3 + 4) +6 = 4 + (3 + 6)

The property used when mutliplying a number times two addends. Ex: 2(5x + 3) = 10x + 6

A vlue that does not change, in a term without a variable. Example: The 8 in this expression: 5x + 8

The answer to a division problem.

Breaking down a composite number into all prime factors.Example: 24 = 2 x 2 x 2 x 3

The property that says you can + or x two or more numbers in any order and the value will be the same. 4 + 3 = 3 + 4

The greatest number that is a factor of two or more whole numbers. Example: 14 and 21 The _____ is 7

A number to the upper right corner of a base, show the amount of times the base is multiplied. Ex: 5² = 5x5

A mathematical phrase that has only numbers and operation symbols. (No equal signs) Example: 4 + 4

Replacing the variable with a number value in an expression. Example: 4 + x (if x = 8) then 4 + 8 would value 12.
