| Term | Definition |
|---|---|
| Variable | A letter that represents an unknown value ; can use any letter. |
| Constant | A term without a variable ; numbers. |
| Coefficient | the number part of a term with variables. |
| Term | A term is either a single number or variable, or numbers and variables multiplied together. |
| Like Terms | 2 or more terms with the same variable or exponent are called like terms. |
| Algebraic Expression | Have at least one variable and one operation. |
| Sum | Answer to a addition problem. |
| Difference | Answer to a subtraction problem. |
| Product | Answer to a multiplication problem. |
| Quotient | Answer to a division problem. |
| Fewer than/ Less than | Subtract and Reverse. |
| How much more/ less | = Subtract. |
| % or fraction of | = Multiply. |
| Each | = Divide |
| Than/ from | = Reverse the order |
| Associative Property | The way in which numbers are grouped when added or multiplied does not change the answer. |
| Commutative Property | The order in which numbers are added to or multiplied does not change the answer. |
| Identity Property of Addition | The sum of an addend & 0 is the same as the addend |
| Identity Property of Multiplication | The product of any factor & 1 is the same as the factor |
| Additive Inverse Property | Adding a number and its opposite will produce a sum of 0 |
| Multiplicative Inverse Property | Multiplying any number and its inverse ( reciprocal ) equals 1 |
| 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 |
| Additive Inverse Property | -5 + 5 = 0 |
| Distributive Property | 4 ( x + 3 ) = 4x + 12 |
| Distributive Property | 16 + 40 = 8 ( 2 + 5 ) |
