| Replacement Set | A set of numbers from which replacements for a variable may be chosen. |
| Simplest Form | An expression is in simplest form when it is replaced by an equivalent expression having no like terms or parentheses. When there are no factors, other than 1; When there are no factors, other than 1, left between terms of an expression. when an expression is replaced by an equivalent expression having no like terms or parentheses. |
| Solution | A replacement value for the variable in an open sentence. |
| Term | A number, a variable, or a product or quotient of numbers and variables |
| Variables | Symbols used to represent unspecified numbers or values |
| Vertical Line Test | If any vertical line passes through no more than one point of the graph of a relation, then the relation is a function |

| Multiplicative Identity | Any number times one equals that number (Nx1=N) |
| Multiplicative Inverse | (mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2 |
| Reflexive Property | Any quantity is equal to itself |
| Symmetric Property | If one quantity equals a second quantity, then the second quantity equals the first |
