| Choosing a variable and deciding what the variable represents. | Defining the variable |
| To multiply a sum by a number , multiply each addend by the number outside the parentheses | Distributive property |
| Expressions that have the same value, regardless of the values of the variable(s). | Equivalent expressions |
| To find the value of an algebraic expression by replacing variables with numbers. | Evaluate |
| In a power , the number that tells how many times the base is used as a factor. In 5 to the power of 3 , the exponent is 3 because 5 to the 3rd power = 5x5x5. | Exoponet |
