Sets can be described in several ways:

  1. Roster Form: This method lists all the elements of the set, such as ( A = {1, 2, 3} ).
  2. Set-builder Notation: This describes the properties that characterize the elements, e.g., ( B = {x | x \text{ is an even integer}} ).
  3. Interval Notation: Used primarily for sets of numbers, such as ( C = [1, 5) ) to indicate all numbers from 1 to 5, including 1 but excluding 5.
