| Term | Definition |
|---|---|
| Identity Property of Addition | When you add zero to a number, you get that same number. Its identity doesn’t change. |
| Identity Property of Multiplication | When you multiply a number by 1, you get that same number. Its identity doesn’t change |
| Commutative Property of Addition | The order of addends doesn’t matter, you get the same sum. "Order Property" |
| Commutative Property of Multiplication | The order of the factors doesn’t matter, you get the same product. "Order Property" |
| Associative Property of Addition | When adding multiple addends, the grouping doesn’t affect the sum, but you CAN"T change the order. |
| Associative Property of Multiplication | When multiplying factors, the grouping doesn’t affect the product, but you CAN"T change the order. |
| Additive Inverse Property | Adding opposites gives you “0 (zero)”. Opposites are positive and negative numbers -4 = 4 = 0 |
| Multiplicative Inverse Property | Multiplying reciprocals gives you “1”. Opposites are whole numbers and their reciprocals. 6 x ⅙ = 1 |
| Multiplicative Property of Zero | Any number multiplied by zero equals zero |
| Distributive Property | We break one factor into two smaller addends, multiply them by the other factor, and then add them up. |
