| 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 with variables. |
| Term | Is either a single number or variable, or numbers and variables multiplied together. Terms are usually separated by addition and subtraction signs. |
| 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 |
| Altogether | means to add |
| how much more/less | means to subtract |
| difference | the answer to a subtraction problem |
| less than | Means to subtract after reversing the order of the problem |
| Product | the answer to a Multiplication problem |
| Fraction/ Percent of | means to Multiply |
| Quotient | the answer to a Division problem |
| each | means to Divide |
| Fewer than | Means to Subtract after reversing the order of the problem |
| per | means 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 are added or multiplied 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 |
| Associative Property | (x+7)+9=x+(7+9) |
| Associative Property | 4(3x9)=(4x3)9 |
| Commutative Property | (x+7)+9=9+(7+x) |
| Commutative Property | 5x6=6x5 |
| Identity Property of Addition | x+0=x |
| Identity Property of Multiplication | 6(1)=6 |
| Additive Inverse Property | -5+5=0 |
| Multiplication Inverse Property | 4x1/4=1 |
| Distributive Property | 4(x+3)=4x+12 |
| Distributive Property | 16+40=8(2+5) |
