Algebra terms
| Term | Definition |
|---|---|
| algebraic expression | An expression that has atleast one variable and one operation. |
| 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 terms | Two or more terms with the same variable or exponent. |
| sum | answer to ann addition problem. |
| difference | answer to a subtraction problem. |
| 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. |
| 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 and 0 is the same as the addend |
| Identity 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 0 |
| Multiplicative Inverse Property | multiplying another number and its inverse 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 | 6x5=5x6 |
| Identity property of addition | x+0=x |
| Identity property of multiplication | 6(1)=6 |
| Multiplicative Inverse property | 4x1/4=1 |
| Additive inverse property | -5+5=0 |
| Distributive property | 4(x+3)=4x+12 |
| Distributive property | 16+40=8(2+5) |
