Algebraic Terms
| Term | Definition |
|---|---|
| Variable | A letter that represents an unknown value (varies); 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 number and variables multiplied together. Terms are usually separated by addition and subtraction signs. |
| Like terms | Two or more terms with the same variable or exponent. |
| Algebraic expression | An expression with at least one variable and one operation. |
| Sum | The answer of numbers being added together |
| altogether | The amount of numbers all put together |
| How much more/less | How much more you should add or subtract. |
| Difference | The answer of a subtraction equasion |
| less than | Subtract |
| Product | The answer of a multiplication problem |
| of | A sign of multiplication ONLY when it is In front of a fraction or percent. |
| Quotient | The answer to a division equasion |
| per | A term used for division |
| each | Divide |
| Than/From | Reverse the order of the expression. |
| 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 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 zero. |
| Multiplicative Inverse Property | Multiplying any number and its inverse (reciprocal) equals one. |
| 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) |
