| Variable | a letter that represents an unknown value; varies; can use any letter |
| Contstant | a term without a variable; numbers |
| Coefficient | the number part of a term with variables |
| Term | either a single number or a variable, or number and variable joined together by variables multiplied together. Terms are usually separated by addition and subtraction sign. |
| Like Terms | Two or more terms with the same variable or exponent |
| sum | means you need to do a addition problem |
| difference | means you need to do a subtraction problem |
| product | means you need to do a multiplication problem |
| altogether | means you need to do a multiplication problem |
| how much more/less | means you need to do a subtraction problem |
| less than | means you need to do a subtraction problem |
| fewer than | means you need to do a subtraction problem |
| of | means you have to do a multiplication problem |
| quotient | means you need to do a division problem |
| per | means you need to do a division problem |
| each | means you need to do a division problem |
| than | means you need to reverse the order of the expression |
| from | means you need to reverse the order of the expression |
| quantity | means you need to use parenthesis to create a group |
| Associative property | the sum or the product of three or more numbers does not change if they are grouped in a different way |
| commutative property | The order in which numbers are added or multiply does not change the answer |
| 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 |
| multiplicative inverse property | multiplying any number and its inverse (reciprocal) equals one |
