| Question | Answer |
|---|---|
| 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 single number or variable, or numbers and variables multiplied together. terms are usually separated by addition and subtraction signs. |
| Like term | Two or more terms with the same variable or exponent |
| algebraic expressions | have at least one variable and one operation |
| sum | answer to a addition equation |
| difference | answer to a subtraction equation |
| product | answer to a multiplication problem |
| quotient | 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 in which numbers are grouped when added |
| 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 and 0 is the same as the addend |
| identify property of multiplication | the product of any factor and 1 is the same as the factor |
| additive inverse property | adding a number and its opposite will produce a sum of zero |
| multaplicative inverse property | multiplying any number and its inverse 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 |
