Algebra terms
| Question | Answer |
|---|---|
| Algebraic expressions | Have at least one variable and one operation. |
| Variables | A letter that represents an unknown value and you can use any value. |
| Constant | a term without a variable; numbers. |
| Coefficient | The number part of a term with variables. |
| Term | A single number or variable or a number and variable multiplied together. Usually separated by addition and subtraction. |
| Like Term | 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 |
| 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) |
| Then | divide |
