This chapter introduces the fundamental concept of sets, which form the base for many topics in higher mathematics. Students learn what a set is, how elements are defined, and the different types of sets used in mathematics. The chapter explains various methods of representing sets, including roster form, set-builder form, and statement form, with clear examples for better understanding.

Emphasis is placed on understanding notation, symbols, and basic set terminology to help students express mathematical ideas accurately. Through step-by-step explanations and practice problems, students develop logical thinking and gain the confidence needed to apply set concepts in problem-solving and future chapters.
