Closure Property for Whole Number Multiplication | If a and b are any two whole numbers, then a x b equals an unique whole number |
Commutative Property for Whole Number Multiplication | a x b x c = a x c x b |
Associative Property for Whole Number Multiplication | (a x b) x c = a x (b x c) |
Distributive Property of Multiplication over Addition | a x (b + c) = a x b + a x c |
Distributive Property of Multiplication over Subtraction | a x (b-c) = a x b - a x c |
Zero product Property | If a x b = 0, then a = 0 or b = 0 |
Multiplication Property of Zero | if a is any number, then a x 0 = 0 and 0 x a = 0 |
Not Possible | Possible? 9/0 |
Possible | Possible? 0/9 |
Identity Property for Whole-Number Multiplication | a x 1 = a and 1 x a = a |
Multiplier | a in a x b = c |
Multiplicand | b in a x b = c |
Repeated Multiplication | When all factors are identical |
Exponential Notation | Writing products with identical factors |
Dividend | a in a / b = c |
Divisor | b in a / b = c |

Division by Grouping | Given the total number of objects and how many objects per group. How many groups? |
Repeated Subtraction Model | Given the total number of objects and how many objects per group. How many groups? (12-4=8, 8-4=4, ect) |
Division Property of Zero | If a is any whole number, then 0 / a = 0 |
