Set theory is a branch of mathematical logic that studies sets, which are collections of objects. It provides a fundamental framework for understanding different mathematical concepts. In set theory, objects are considered as a single unit, and the focus is on their properties and relationships. The theory explores concepts like the formation of sets, the relationships between sets (such as subsets, unions, and intersections), and operations on sets. It also deals with the size of sets (cardinality) and the notion of infinity. Set theory forms the basis for many areas of mathematics, including algebra, geometry, and probability, and it plays a key role in the foundation of mathematics itself.
