Class 10 Mathematics starts with Chapter 1 Real Numbers. In this chapter, you’ll learn about the core concepts related to real numbers. Here are the main topics and core concepts covered in Chapter 1 of Class 10 Mathematics. Understanding the concept of real numbers, which include all rational and irrational numbers. Learning about Euclid’s Division Lemma and how it helps in understanding the properties of divisors and remainders. Studying the Fundamental Theorem of Arithmetic, which states that every positive integer can be expressed uniquely as a product of prime numbers.
