Commutative Property of Multiplication | The order of factors can be changed and the product remains the same. Example: 3* 3* 5 = 5 * 3* 3 |
Associative Property of Multiplication | Factors can be regrouped and the product remains the same. Example: 2 *(4 *10) (2 * 4)* 10 |
Identity Property of Multiplication | The product of any number and 1 is that number. |
Zero Property of Multiplication | The product of any number and 0 is 0. |
factors | Numbers that are multiplied to get a product |
product | The number that is the result of multiplying two or more factors |

base | The number that is multiplied by itself when raised to a power Example: In 53, the 5 is the base. |
exponent | A number that tells how many times the base is used as a factor Example: 103 5 10 × 10 × 10; the exponent is 3 and the base is 10. |
