Profit and Loss

Through this chapter, we will understand the concepts related to percentage. It discusses the key concepts and idea of percent as a fraction with 100 as the denominator. It also highlights how to find the percentage of a given number.

Percentage

This topic discusses the concepts of linear equations and pairs of scales. It explains how to solve the equations with different data. It also includes examples and exercises for a better understanding.

Linear Equations

This chapter sheds light on factorisation. We will acquire knowledge about the method of factorisation of cyclic expressions. We will understand the concept of cyclic expressions and cyclic factors through various examples.

Factorisation

This chapter sheds light on algebraic expressions which consist of at least one variable and at least one operation. We will also learn how to add, multiply and subtract algebraic expressions with the aid of examples and exercises.

Operations on Algebraic Expressions

This chapter unfolds the notion of divisibility rule of 2, 3, 5, 6, 9 and 10. Further, it explores the concept of factors, multiples, prime numbers and composite numbers. We will also study the relationship between LCM and HCF through examples.

Playing With Numbers

This chapter talks about perfect cubes, the properties of cubes, and cubes of different kinds of numbers. It also specifies steps to see if a number is a perfect cube, and the operations to find the cube roots of numbers using different methods.

Cubes and Cube Roots

This chapter gives an introduction to square numbers and their squares. Here, we discuss how to check perfect squares and the properties of perfect squares. We understand square roots and methods to find the square roots through examples.

Squares and Square Roots

This chapter sheds light on the concept of exponents. The laws of exponents, such as multiplying terms with the same base, division of exponent, and exponent of a product are discussed here in detail.

Exponents
