Algebra Terms
| Term | Definition |
|---|---|
| Algebraic Expressions | They have at least one variable and one operation. |
| Variable | A letter that represents an unknown value. |
| Constant | A term without a variable. |
| Coefficient | The number part of a term with variables. |
| Term | A single number or variable, or numbers and variables multiplied together. They are normally separated by addition and subtraction signs. |
| Like terms | Two or more terms with the same value or exponent. |
| Sum | The result or answer after adding two or more numbers or terms. |
| Altogether | Adding together. |
| How Much More/Less | Subtraction. |
| Diffrence | Subtraction. |
| Less Than | Subtraction, reverse. |
| Product | Multiplication, also the answer to the problem. |
| Of | Multiplication, multiply if there is a fraction or percentage in front. |
| Quotient | Division, also the answer to the problem. |
| Per | Division. |
| Each | Division. |
| Fewer Than | Subtraction, reverse. |
| Than or 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 or multiplied does not change the answer. |
| Identify Property of Addition | The sum of an addend & 0 is the same as the addend. |
| Identify 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(3x9) = (4x3)9 |
| Commutative Property | (x + 7) + 9 = 9 + (7+x) |
| Identity Property of Addition | x + 0 =x |
| Commutative Property | 5 x 6 = 6 x 5 |
| 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) |
