​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!​

Multiplying the SAME variables gives them an exponent by how many of those variables you multiplied together.​

​x ⋅ x = x²

Multiplying two DIFFERENT variables together means they essentially​ become "stuck together" by multiplication.

​x ⋅ y = xy

Multiply the two coefficients, then "stick" the variables together using multiplication.​

​2x ⋅ 2y = 4y

A lonely variable means there is a "1" in front of it.

​

Multiplying two DIFFERENT variables together means they essentially​ become "stuck together" by multiplication.
