0Set theory, a fundamental concept in mathematics, deals with the properties and relationships of well-defined collections of objects, known as sets. For JEE Main, it's crucial to understand the basics of sets, including different types, operations like union and intersection, and their representation using set-builder notation. Understanding concepts like subsets, power sets, and Venn diagrams is also essential for solving problems in this area
