6th Grade Math: Module 6 Equations (vocabulary)

When three numbers are grouped does not change their sum or product: 2 + (3 + 1) = (2 + 3) + 1

A term without a variable; unchanging

What is the solution to the equation? b - 4 = 8

A mathematical sentence showing two expressions are equal

When (+) or (-) signs separate an algebraic expression into parts

The value of a variable that makes an equation true

Which property is used to solve 6x = 12?

Mathematical language of symbols, including variable

The order in which two numbers are added or multiplied does not change their sum or product ( 3 + 4 = 4 + 3 )

If you subtract the same number from each side of an equation, the two sides remain equal.

A symbol, usually a letter used to represent a number

Addition equations use which inverse operation when solving?

The numerical factor of a term that contains a variable (Example: 3n.......what is 3 called?)

To multiply a sum by a number, multiply each addend by the number outside the parenthesis *Ex: 2(3 + 4m) = 6 + 8m

Operations which undo each other

"If you multiply the same number to both sides of an equation, the two sides remain equal"

Division equations use which inverse operation when solving?

Subtraction equations use which inverse operation when solving?

Multiplication equations use which inverse operation when solving?
