| Term | Definition |
|---|---|
| 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 without variables |
| term | either 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 | at least one variable and one operation |
| sum | the answer to an addition problem |
| altogether | meaning to add |
| how much more/less | meaning to subtract |
| difference | the answer to a subtraction problem |
| fewer than/ less than | meaning to subtract but reverse the order |
| product | the answer to a multiplication problem |
| of | meaning to multiply only when it occurs right after a fraction or percent |
| quotient | the answer to a division problem |
| per | meaning to divide |
| each | meaning to divide |
| than/from | reverse the order of the expression |
| 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 |
| 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 |
| Multaplicative 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) |
