The first chapter of Class X Mathematics, “Real Numbers,” introduces students to the fundamental concept of real numbers, which form the basis for various mathematical operations and concepts. In this chapter, students will learn about:
- Real Numbers: Understanding what real numbers are and their properties.
- Euclid’s Division Lemma: Learning about Euclid’s division lemma and its significance in number theory.
- Fundamental Theorem of Arithmetic: Exploring the fundamental theorem of arithmetic and its implications for prime factorization.
- The HCF and LCM: Calculating the highest common factor (HCF) and least common multiple (LCM) of numbers.
- Irrational Numbers: Identifying and understanding irrational numbers.
- Decimal Expansions: Learning about decimal expansions and their properties.
- Real Numbers on the Number Line: Representing real numbers on the number line.
- Operations with Real Numbers: Performing operations such as addition, subtraction, multiplication, and division with real numbers.
This chapter serves as a foundation for the understanding of various mathematical concepts and operations. It also paves the way for exploring more advanced topics in number theory and algebra.
