Detailed Explanation of the Important Chapters for CBSE Class 10 Maths Board Exams 2026
Let’s understand each chapter in simple words.
1. Real Numbers
It is a straightforward chapter and is largely formula-based. The questions are based on the division lemma of Euclid, HCF, LCM, and irrational numbers. You will find it easy to score full marks in case you practice some standard questions.
2. Polynomials
You will receive questions concerning zeroes of polynomials, relationship between coefficients and drawing graphs. The chapter appears lengthy, although, the majority of questions are highly predictable. You can practice your 10 maths book of the cbse.
3. Two Linear Equations in Two Variables.
Chapter of importance in word problems. You will be taught substitution method, elimination method and cross- multiplication method. These questions are highly scoring when your steps are in order.
4. Quadratic Equations
It is one of the most significant chapters. You will have questions on factorisation, checking the nature of roots and solving equations using quadratic formula. This chapter is quite easy in case formulas are memorised properly.
5. Arithmetic Progressions
The paper normally has AP questions that are the easiest to answer. Common are finding nth term, sum of n terms or word problems. This chapter is popular among students as it contains easy formulas.
6. Triangles
It is a large Geometry chapter and it carries a lot of marks. You should know about similarity of triangles, Pythagoras theorem and ratio questions. The evidences might seem hard to understand initially, but with practice they become easy.
7. Coordinate Geometry
The most frequently asked questions are distance formula, section formula and area of triangle. They are highly formulaic and simple to mark.
8. Surface Areas & Volumes
Chapter of real-life applications. You will have questions involving cones, cylinders, spheres, and combinations of shapes. Diagram practice helps a lot.
9. Statistics
The questions of mean, median and mode are quite common. Graph questions can also be received. It is among the simplest chapters in the syllabus.
10. Probability
This chapter is very scoring as the questions are founded on very simple concepts such as dice, cards and coins. Many students like it as one of their favourite chapters.
