| 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 |
