| Order of operations | A rule for evaluating expressions: first perform the operations in parentheses, then compute powers and roots, then pform all multiplication and division from left to right, then perform all addition and subtraction from left to right |
| Commutative property | You can add numbers in any order and multiply numbers in any order |
| Associative property | When you add or multiply, you can group the numbers together in any combination |

| Inverse operations | Operations that undo each other |
| Subtraction property of equality | You can subtract the same amount from both sides of an equation and the statement will still be true |
