In this chapter, students will learn about sets and their different representations, which help in understanding and organizing mathematical information clearly. They will study the roster form and the set-builder form of representing sets, and understand when each form is more appropriate to use.

Students will also explore important types of sets such as the empty set, finite sets, and infinite sets, along with their properties. The chapter further explains the concept of equal sets, helping students compare collections logically. This chapter strengthens foundational knowledge required for advanced topics like relations, functions, and probability.
