Editing Operations on sets

= Operations on Sets - Overview and Basic Definitions =

'''Operations on sets''' are procedures that combine or modify sets to form new sets. They are fundamental in set theory and are widely used in mathematics, computer science, and logic.

== Basic Set Operations ==

Here are the most common operations on sets with brief explanations:

* '''Union (∪)''': The union of two sets <math>A</math> and <math>B</math> is the set of all elements that are in <math>A</math> or <math>B</math> or in both.

<math>A \cup B = \{x : x \in A \text{ or } x \in B\}</math>

* '''Intersection (∩)''': The intersection of two sets <math>A</math> and <math>B</math> is the set of all elements that are in both <math>A</math> and <math>B</math>.

<math>A \cap B = \{x : x \in A \text{ and } x \in B\}</math>

* '''Difference (−)''': The difference of two sets <math>A</math> and <math>B</math> (also called the '''relative complement''') is the set of all elements that are in <math>A</math> but not in <math>B</math>.

<math>A - B = \{x : x \in A \text{ and } x \notin B\}</math>

* '''Complement (′)''': The complement of a set <math>A</math> relative to a universal set <math>U</math> is the set of all elements in <math>U</math> that are not in <math>A</math>.

<math>A' = U - A = \{x : x \in U \text{ and } x \notin A\}</math>

== Summary ==

Understanding these set operations is essential for working with sets in various mathematical contexts. They help in analyzing relationships between groups of elements and are the foundation for more advanced concepts.
