In this chapter, students will learn the basic idea of sets as collections of well-defined objects. They will understand and explain important concepts such as subsets, power sets, and the universal set, which form the foundation of higher mathematics. The chapter also introduces Venn diagrams as a visual tool to represent sets and their relationships clearly.

Students will further learn to perform operations on sets, with special focus on the union of sets, and interpret these operations using Venn diagrams. This chapter helps in developing logical thinking, symbolic representation, and conceptual clarity, which are essential for advanced topics in relations, functions, probability, and calculus.
