Number System

This chapter discusses the various operations on sets and their representation methods. It briefly explains the classification of sets, complements of sets, cardinal numbers of sets, union and intersection of sets and Venn diagrams, among other ideas.

This chapter deals with the properties of rational numbers, their standard form and their representation on the number line. It briefly discusses the arithmetic operations on rational numbers and finding a rational number between two rational numbers.

In this chapter, we will study the method of expressing the product of a number in exponential notation. It also explains the laws of exponents and the negative power of exponents through elaborative solved problems.

This chapter deals with the concepts of decimal numbers, square numbers and square roots. We will learn about the perfect squares and their properties. It also discusses the method of checking if a number is a square number or not and finding the square root of a number.

This chapter discusses the method of finding the cube of a number through the prime factorisation method. It also helps us identify whether a given number is a perfect cube or not.

This chapter explains the factors and multiples of a number. It also discusses the different types of numbers, and explains how to write numbers in generalised form and test the divisibility of numbers by other numbers. Besides, we learn the concept of prime factorisation.
