identification 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 |

partial products | Products found by breaking one of two factors into ones, tens, hundreds, and so on, and then multiplying each of these by the other factor |
base | The number that is multiplied by itself when raised to a power |
