| Quotient | Answer to a division problem. |
| Product | Answer to a multiplication problem. |
| less than / fewer than | subtract + reverse |
| each | divide |
| than/from | reverse the order |
| algebraic expression | have at least one variable and one operation |
| % or fraction of | multiply |
| how much more/less | subtract |
| like terms | two or more terms with the same variable or exponent |
| Communicative Property | The order in which numbers are added or multiplied dose not change the answer |
| Associative Property | The way in which numbers are grouped when added or multiplied dose not change the answer. |
| Identity Property of addition | The sum of an addend & 0 is the same as the addend. |
| Additive Inverse Property | Adding a number and its opposite will produce a sum of zero. |
| Multiplicative Inverse | Multiplying any number and its inverse ( reciprocal) equals one. |
| Identity Property of multiplication | the product of any factor & 1 is the same as the factor |
| Associative Property | (x + 7)+ 9 = x + (7 + 9) |
| Associative Property | 4 (3 x 9) = (4 x 3) 9 |
| Commutative Property | ( x + 7 ) + 9 = 9 + ( 7 + x ) |
| Commutative Property | 5 x 6 = 6 x 5 |
| Identity Property of Addition | x + 0 = x |
| Identity Property of Multiplication | 6 (1) = 6 |
| Multiplicative Inverse Property | 4 x 1/4 = 1 |
