algebra terms
| Question | Answer |
|---|---|
| variable | a letter that represents an unknown value. It can vary. Any letter works. |
| constant | a term without a variable. AKA numbers |
| coefficient | the number part of a term with a variable |
| term | a single number or variable,or numbers and variable multiplied together. Usually separated by addition or subtraction signs. |
| like terms | 2 or more terms with the same variable or exponent are called like terms |
| algebraic expression | a problem with at least one variable and one problem |
| sum | the answer to a 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 |
| % of a fraction | multiply |
| each | divide |
| is than/ from | reverse the order |
| associative property | the way which numbers are grouped when added or multiplied does not change the answer. |
| commutative property | the order in which numbers are multiplied or added does not change the answer. |
| ID property of addition | any thing plus 0 keeps its identity |
| ID property of multiplication | anything multiplied by one keeps its identity |
| additive inverse property | adding a number and its opposite will produce a sum of 0 |
| multiplicative inverse property | multiplying any thing by 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 | 5x6=6x5 |
| ID prop of addition | x+0=x |
| ID prop of multiplication | 6(1)=6 |
| multiplicative inverse prop | 4x1/4=1 |
| additive inverse prop | -5+5=0 |
| distributive prop | 4(x+3)=4x+12 |
| distributive prop | 16 + 40 =8(2+5) |
