| algebraic expression | an expression that contains at least one variable |
| coefficient | the number that is multiplied by the variable in an algebraic expression |
| constant | a value that does not change |
| evaluate | to find the value of a numerical or algebraic expression |
| substitute | to replace a variable with a number or another expression in an algebraic expression |
| variable | a symbol used to represent a quantity that can change |
| equation | a mathematical expression that shows that two expressions are equivalent |
| solve | to find an answer or solution |
| solution of an equation | a value or values that makes an equation true |
| inverse operations | operations that undo each other |
