A number standing on its own in an expression​

​Constant

Each piece of an expression that is separated by + or - signs (sometimes division).​

​Term

​KEY VOCABULARY

Take Away: Terms are separated by +/-, and constants are LONELY!​

An unknown represented by a letter in an expression.​

​Variable

A number attached to a variable by multiplication.​

​Coefficient

​KEY VOCABULARY

Take Away: Coefficients are attached to variables, and variables are letters!

The number connected to the OUTSIDE of the parentheses is "shared" BY MULTIPLICATION with all variables, constants, and coefficients on the INSIDE of the parentheses.​

​

​KEY TERMS: Constant | Variables | Coefficient

​Distribute = SHARE

​

​Distributive Property

​Draw your arrows, then multiply.

You are able to keep up with what terms to multiply when using the distributive property when you draw your arrows FIRST.​

Take Away: ALWAYS, ALWAYS DRAW YOUR ARROWS FIRST!​

How to Solve!

Get rid of the 3rd Wheel: Add or Subtract to get rid of the number

Break up the happy couple: Multiply or Divide both sides of the equation by the coefficient

When you see an equation with variables on both sides you should:

• Move all the terms with variables to one side of the equation by making the term zero on one side.

• Remember that terms with variables can become zero the same way constants become zero: by adding the opposite or using the inverse operation.

• The equation stays balanced when you do the same thing to both sides.

It could look like this:
