Question | Answer |
---|---|
counting #s | 1,2,3...ect |
whole #s | 0,1,2,3...ect |
Intergers | ect...-2,-1,0,1,2...ect |
rational #s | any term which can be expresses as a numerator over a denominator |
Irrational #s | any term that cannot be written as a numerator over a denominator |
order of operations | ( ), exponents, X or / left to right, + or - left to right |
Commutative property | order makes nodifference |
Associative | grouping using minimum of 3 terms for + or x |
Distributive | multiply the term DIRECTLY outside |
Reciprocal | any term times its reciprocal is 1 |
Identity of addition | any number plus 0+itself |
Identity of multiplication | any # times 1=itself |
Opposite | any term plus its opposite is 0 |
addition | if the signs are the same add and give the awnser in the same sign. if the terms are different subtract and give the awnser of the larger# |
subtraction | add the opposite of the 2nd term |
multiplication/division | both terms have same sign = posotive if terms have different signs = negative |
Absolute value | the distance between a # and 0 |
variable | is used to represent an unknown # |
opposite | if the # is possotive than the negative version of it and if the # is negative then the posotive version of it. Ex -1=1 2=-2 |
solution | the awnser |
equation | a mathmatical problem |
absolute value | how far away from 0 the # is |
Reciprocal | the opposite of a # for example 2/1=1/2 |
like terms | same base same exponent |
