| System of Linear Equations | Two or more linear equations with no common, one common or infinitely many common solutions |
| Range | A complete set of y-values of a function |
| Extraneous Solution | Math Solutions not necessary to solve the problem |
| Associative Property | Adding or Multiplying values or algebraic expressions in any order: (A + B) + C = A + (B + C) |

| Quotient | Answer to Division |
| Distributive Property | The product of a number and the sum or difference of two numbers is equal to the sum or difference of the two products. A(B + C) = AB + AC |
| Order of Operations | PEMDAS: Parenthesis, Exponents, Multiplication/Division from left to right, Addition/Subtraction from left to right |
