| PEMDAS | Please Excuse My Dear Aunt Sally |
| Order of Operations | Parentheses, Exponents, Multiplication, Division, Addition, Subtraction |
| Algebraic Expression | a group of numbers and terms without an equation sign, Ex. 2x + 8 |
| variable | an unknown |
| commutative property | Changing the order of numbers. For Ex. 2 + 3 = 3 + 2 |
| associative property | Changing the grouping of numbers. For Ex. (2 + 3) + 4 = 2 + (3 + 4) |
| identity property | In addition, adding zero; In multiplication, multiplying by 1 |
| zero property | In multiplication, multiplying by zero gives you zero. In addition, adding zero gives you the original number |
| Equation | A group of terms with an equal sign. For Ex. 2x + 8 = 20 |
| Inverse Operation | The opposite operation. For Ex. Multiplication & Division, Addition & Subtraction |
| Coordinate Plane | The place where you graph ordered pairs. |
| X-Axis | The horizontal axis |
| Y-Axis | The vertical axis |
| Origin | (0,0) |
| Ordered Pair | Includes an x-coordinate and a y-coordinate in between parentheses. For ex. (2,3) |
| X-coordinate | The first term in an ordered pair |
| Y-coordinate | The second term in an ordered pair |
| Quadrant | One of the four corners that the coordinate plane is split into |
| Plot | to graph |
