algebra terms
| Question | Answer |
|---|---|
| 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 |
| terms | a single number or variable , or numbers and variables multiplied together |
| like terms | two or more terms with the same variable or exponent |
| Algebraic expression | have at least one variable and one operation |
| sum | the answer to an addition problem |
| difference | the answer to an subtraction problem |
| product | the answer to an multiplication problem |
| quotient | the answer to an division problem |
| fewer than/less than | To subtract and reverse the expression |
| how much more/less | to subtract |
| % or fraction of | to multiply |
| each | to divide |
| than/from | to reverse the order of the expression |
| Communicative Property | the ORDER in which numbers are added or multiplied does not change the answer |
| Associative Property | The way in which numbers are GROUPED when 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 |
| QUICK TIP | In both properties, the original numbers keeps its IDENTITY |
| Additive inverse | Adding a number and its opposite will produce a sum of zero |
| Multiplicative inverse | 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) |
