| A | B |
|---|
| Equivalent decimals | Decimals that name the same amount |
| Approximation symbol | "Approximately equal to" |
| Repeating decimals | The result of dividing a decimal and the quotient continues to repeat |
| Compatible numbers | Numbers that are easy to divide mentally |
| Identity Property of Addition | Any number plus zero equals that number. (eg. 6 + 0 = 6) |
| Commutative Property of Addition | Changing the order of the addends does not change the value of their sum. (eg. 7 + 6 = 6 + 7) |
| Associative Property of Addition | Changing the grouping symbols of the addends does not change the value of their sum. (3 + 4) + 12 = 3 + (4 + 12) |
| Identity Property of Multiplication | Any number times 1 equals that number itself. (eg. 14 x 1 = 14) |
| Zero Property | Any number times zero is zero. (9 x 0 = 0) |
| Commutative Property of Multiplication | Changing the order of the factors does not change the value of their product. (eg. 9 x 3 = 3 x 9) |
| Associative Property of Multiplication | Changing the grouping symbols of the factors does not change the value of their product. eg. (8 x 4) x 5 = 8 x (4 x 5) |
| Distributive Property | Multiplying the factor times each addend inside the grouping symbols does not change the value of the product. Example 8(4 + 5) = 8(4) + 8(5). |
| Terminating decimal | The result of dividing a decimal and the quotient stops |
