This chapter focuses on the fundamental operations performed on sets, including union, intersection, and difference of sets. Students learn how these operations combine or relate sets and how they are applied to solve mathematical problems. The use of symbols and proper notation is explained clearly to strengthen conceptual understanding.

Special emphasis is given to solving problems using Venn diagrams, which help visualize relationships between sets. Through step-by-step examples and practice questions, this chapter builds logical thinking and prepares students to confidently handle exam-oriented questions involving set operations.
