Overview
Mathematics is a learning that is very important in many endeavors and careers. To students in Class 10, it is extremely significant to progress through the mathematics syllabus established by NCERT since it enables one to score better during examinations and adequately prepares him/her for advanced levels. This basic understanding provides a strong basis for different aspects of Mathematics using its various topics and exercises provided in the NCERT textbook for Class 10 Mathematics.
This post will focus on providing relevant solutions to chapters of the NCERT Class 10 Maths. For some of you who may have algebra, geometry, or even trigonometry difficulties, this guide is intended to make such topics less difficult and more practical. We will discuss each chapter in turn and explain why it matters, as well as how you can solve its problems to get the most out of it.
Chapter 1: Real Numbers
Key Concepts
- Euclidean division algorithm
- Fundamental Theorem of Arithmetic
- On Irrational Numbers Through the Lattice of Rational Numbers
- On Rational Numbers and Their Decimal Expansions
Solutions Overview: The chapter starts with a clear description of the steps of Euclid’s division algorithm and the application of the division algorithm in the cases of HCF. Next, we go to areas of prime importance, beginning with the Fundamental Theorem of Arithmetic, which defines the scope of a prime number factorization. Also in this chapter are irrational numbers, their definitions, and how they are constructed. In the very last section, we focus on rational numbers and show their decimal equivalents, both the terminating and the repeating non-terminating decimals.
Tips for Students:
- Make sure that you go through the examples given before applying the ideas in the exercises.
- Keep in your head the characteristics of irrational and rational numbers, as it is a common examination of students.

The chapter also extends to the polynomial division that is, dividing a polynomial by another and finding the remainder.
Tips for Students:
- Don’t forget about the graphical representation of polynomials since it enables contrast.
