| FINITE SET | HAS A COUNTABLE NUMBER OF ELEMENTS > FOR EXAMPLE { 1 , 2 , 3 , 4 , 5 , } . FINITE SETS CAN ALSO BE DEFINED IN A MANNER THAT DOES NOT REQUIRE THE ELEMENTS TO BE LISTED > EXAMPLE : D = { DAYS OF THE WEEK } |
| BRACES | { } USED TO INDICATE SETS IN THE STUDY OF MATH |
| EMPTY SET | CONTAINS NO ELEMENTS { } AND IT IS A FINITE SET > EXAMPLE : A SET REPRESENTING THE MONTHS OF THE YEAR WITH 35 DAYS |
| INFINITE SET | HAS AN UNCOUNTABLE NUMBER OF ELEMENTS > EXAMPLES : { ... - 2 , - 1 , 0 , 1 , 2 } , { 1 , 2 , 3 , 4 , } , AND { 0 , ... , 1/8 , 1/4 , 1/2 , 1 } . ALSO , LIKE FINITE SETS , THE SET CAN BE DEFINED WITHOUT THE ELEMENTS BEING LISTED > EXAMPLE : R = { REAL NUMBERS BETWEEN ONE AND TWO } |
| ELEMENT | TERM USED IN MATH TO DESCRIBE ITEMS IN A SET |
| THREE DOT NOTATION ... | USED IN BOTH FINITE AND INFINITE SETS MEANING THAT EITHER THE SET CONTINUES FOREVER { 1 , 2 , 3 , 4 , ... } OR A FINITE SET { 1 , 2 , 3 , 4 , ... , 20 } MEANING ALL THE WHOLE NUMBERS BETWEEN 1 AND 20 |
