Algebra Terms
Terms to know for math!
| Question | Answer |
|---|---|
| Algebraic Expressions | They have at least one variable and at least one operation. |
| Variable | A letter that represents an unknown value (varies); can use any letter. |
| Constant | A term without and variable; numbers. |
| Coefficient | The number part of a term with variables. |
| Term | It is either a single number or variable, or numbers 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. |
| sum | The answer to a addition problem. |
| difference | The answer to a subtraction problem. |
| product | The answer to a multiplication problem. |
| quotient | The answer to a division problem. |
| fewer than/ less than | Subtract and reverse. |
| How much more | Less- subtract. |
| % or fraction of | Multiply. |
| Each | Divide. |
| Is than/ from | Reverse the order. |
| Associative Property | The way 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 it's opposite will produce a sum of zero. |
| Multiplicative Property | Multiplying any number and it's inverse (reciprocal) equals one. |
| Associative Property | EX: (x+7)+9=x+(7+9) |
| Associative Property | EX: 4(3x9)= (4x3)9 |
| Commutative Property | EX: (x+7)+9=9+(7+x) |
| Commutative Property | EX: 5x6=6x5 |
| Identity Property of Addition | EX: x+0=x |
| Identity Property of Multiplication | EX: 6(1)=6 |
| Multiplicative Inverse Property | EX: 4x1/4=1 |
| Additive Inverse Property | EX: -5+5=0 |
| Distributive Property | EX: 4(x+3)= 4x+12 |
| Distributive Property | EX: 16+40=8(2+5) |
