A set in mathematics is a collection of well defined and distinct objects, considered as an object in its own right.
Sets are one of the most fundamental concepts in mathematics. Developed at the end of the 19th century, set
theory is now a ubiquitous part of mathematics, and can be used as a foundation from which nearly all of
mathematics can be derived. In mathematics education, elementary topics such as Venn diagrams are taught at a
young age, while more advanced concepts are taught as part of a university degree
