Abstract
A set is a collection of objects called elements. If x is an element of a set X, we write this as x ∈ X. We can construct a set by listing the elements X = {x|x has some property}. The set with no elements is called the empty set and is denoted by ∅. If X is a finite set, then #X denotes its number of elements.
