2 ways of naming a set:
1.) Roster method
- elements are put inside the braces to represent a set
Ex. U= {1, 3, 5, 7, 9, 11}
2.) Set builder
- instead of putting elements on the set, the set builder uses description to represent the elements present inside the set.
Ex. {x|x>16}
(this time, we know that this set has the elements x, such that x that is greater than 16)
