The Probability is an important topic, even in higher classes.

Chapter 6: Square and Square Roots

In Class 8 Maths Chapter 6, we will learn how to find square or square roots of a number. In Exercise 6.1, most of the questions are based on hit and trial method or successive addition method. Exercise 6.2 is related to find the square of a number by just multiplying the number to itself or using the Binomial Formula of expansion. A brief intro about Pythagoras Triplet is also given in the second exercise. In Exercise 6.3, we have to find square roots of a number by successive subtraction or using Prime Factorisation method. Exercise 6.4 is designed to find the square roots using division methods as well as by estimation. Here we can find the square roots of decimal numbers also.

Chapter 7: Cube and Cube Roots

In Class 8 Maths Chapter 7, we will discuss with the cubes of a number and its cube root also. Exercise 7.1 explain the method of finding cube by adding a consecutive odd number or by using prime factors. Questions related to cube roots are given in Exercise 7.2 of Class 8 Maths. We can also find the cube root of a number using its Prime Factorisation.

The description of mapping places and spaces are given in Exercise 10.2 of Class 8 Maths. In Exercise 10.3, we will learn to find out the Edges, Faces and Corners or Vertices of a 3 – D object. Euler's Formula (F + V – E = 2) is important in this exercise. Most of the time, a question based on Euler's Formula is asked in school exams.

Chapter 11: Mensuration

Class 8 Maths Chapter 11 Mensuration is not only the main topic for class 8, but it is important for further classes also. Exercise 11.1 contains only five questions, in which the 5th question is tricky. In Exercise 11.2, we will deal with the areas related to Trapezium and another quadrilateral, when the perpendicular to the side or diagonal is given. Next step is to find the surface area of solid figures in Exercise 11.3 of Class 8 Maths. Here, we will learn to find out the areas of Cube, Cuboid, Cylinder, Sphere, Hemi-sphere or Cone. The volume of these 3 – D figures can be obtained using the formulae used for Exercise 11.4 in 8th Maths.

Chapter 12: Exponents and Powers

In Class 8 Maths Chapter 12, we will study the numbers having negative or positive powers. Exercise 12.1 is based on the Laws of Exponents. Questions 5, 6 and 7 are important for exams. The second exercise explains about the Scientific Form or Standard Form. In Exercise 12.2, we convert the numbers in the standard form with the help of exponents.

Chapter 13: Direct and Inverse Proportions

Class 8 Maths Chapter 13, we have to check whether the value of both the quantities are increasing or one is increasing and other is decreasing. Exercise 13.1 has the questions of Direct Proportion, where the two quantities increase or decrease together. Similarly, Exercise 13.2 also deals with Inverse Proportion, where one value is increasing, but other is decreasing. The second exercise also contains the questions where Direct and Inverse are implemented in the same question.

Chapter 14: Factorization

In Class 8 Maths Chapter 14, we will study about factors of natural numbers as well as algebraic expressions. In Exercise 14.1, we will make factors by regrouping the terms, whereas, in Exercise 14.2, identities are the main tool for Factorisation. Division of algebraic expression by monomial or polynomial is important for class 8th students. Exercise 14.3 contains questions based on the division of polynomials by another polynomial. At last, in Exercise 14.4, there some errors given in equations. Students have to remove these errors to make the equations or identities true.
