| Question | Answer |
| Associative Property of Addition | When three or more numbers are added, the sum is the same regardless of the grouping of the addends. For example (a + b) + c = a + (b + c) |
| Associative Property of Multiplication | When three or more numbers are multiplied, the product is the same regardless of the order of the multiplicands. For example (a x b) x c = a x (b x c) |
| Commutative Property of Addition | When two numbers are added, the sum is the same regardless of the order of the addends. For example a + b = b + a |
| Commutative Property of Multiplication | When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For example a x b = b x a |
| Distributive Property | The sum of two numbers times a third number is equal to the sum of each addend times the third number. For example a x (b + c) = a x b + a x c |
| Identity Property of Addition | The sum of any number and zero is the original number. For example a + 0 = a. |
| Identity Property of Multiplication | The product of any number and one is that number. For example a x 1 = a. |
| Additive Inverse of a Number | The additive inverse of a number, a is -a so that a + -a = 0. |
| Multiplicative Inverse of a Number | The multiplicative inverse of a number, a is 1/a so that a x 1/a = 1. |
