algebraic expression
| 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 |
| like terms | two or more terms with the same variable or exponent |
| algebraic expressions | at least one variable and one operation |
| product | the answer to a multiplication problem |
| quotient | the answer to a division problem |
| sum | the answer to a addition problem |
| difference | the answer to a subtraction problem |
| how much more/ less | means to subtract |
| fewer than/ less than | subtract in reverse order |
| % or a fraction of | means to multiply |
| each | divide |
| than/from | reverse the order |
| 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 0 |
| Multiplicative Inverse property | multiplying any number and its inverse equals 1 |
| 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 |
