In addition to this, students will also learn how to calculate the area and volume of cubes and cuboidal structures using various formulae. Students must ensure that they solve all the questions included in the exercises of this chapter.

Students in this chapter get to be familiar with the concepts of powers and exponents positive as well as negative. Expressing numbers in standard form by making use of exponents and comparisons of very large with very small numbers is also an integral part of this chapter. To understand this chapter, practise the exercises which include:. The exercises provided contains questions involving both the scenarios and students must attempt to solve them all.

The factorisation of algebraic expressions and natural numbers is dealt with in this chapter. Students learn how to factorise using factorisation identities, regrouping terms, etc. Moreover, students also learn how to divide a polynomial or a monomial by a monomial and more.

Make sure you practise all the 34 questions distributed among the various exercises of this chapter. Since students have already been introduced to the concept of data handling earlier, this chapter primarily focuses on representing data in different types of graphs such as pie charts, histograms, linear graphs, etc.

This chapter takes the challenge up a notch as students learn how to locate points and coordinate them on a graph. To gain confidence in this chapter practice is key which you can achieve by solving all the questions of the exercises.

The chapter acts as a culmination of the concepts that students learn with respect to numbers. The broad genre of numbers has been discussed in detail in this chapter and students can use the concepts to justify the test of divisibility.

The two exercises of this chapter include a total of 14 questions. The Class Maths marks weightage has been provided below according to the chapters and the corresponding marks they carry in the exam.

The knowledge of uni-wise marks distribution is very important as it allows students to formulate their preparation strategy accordingly. Chapter No. Chapter 1. Chapter 2. Chapter 3. Chapter 4. Chapter 5. The next section of this chapter deals with another method of factorization.

Chapter 14 Class 8 explains that while finding the factors of the given expression, we will take an individual term as common and consider it as a common factor. This can be done by forming two groups. For an instance,. Exercise Here students need to find out the identical terms and then separate those terms which give the factors directly. This is the 4th method of solving factorization.

The Class 8 Maths Solutions Chapter 14 explains that this method was usually used if the expression doesn't have perfect squares. Even though it is suitable for perfect squares, without having perfect squares, also we can use this method to get factors of the given expression. Even though we have different methods to find factors, the solution is one and the same, but the procedures may differ.

As the students have learned addition, subtraction, multiplication of algebraic expressions, now class 8 maths factorization explains how to divide two or more expressions.

But it has two sub-concepts. Let A and B be two sets. Types of Relations. Let f be a function from A to B. If every element of the set B is the image of at least one element of the set A i. Otherwise we say that the function maps the set A into the set B. Functions for which each element of the set A is mapped to a different element of the set B are said to be one-to-one.

A function can map more than one element of the set A to the same element of the set B. Such a type of function is said to be many-to-one. A function which is both one-to-one and onto is said to be a bijective function. The order of the elements is taken into consideration, i.
