Algebra

In this chapter, we learn that expansion is the process in which the contents of brackets are evaluated. We also learn to derive identities for various expansions, followed by a lot of examples to understand the concept clearly.

This chapter explains that factorisation is the process of writing an expression in the form of terms or brackets multiplied together. Different methods of factorisation are discussed here with solved examples.

In this chapter, we learn to solve simultaneous equations by the method of elimination by substitution or by equating coefficients. We also learn to solve simultaneous equations by cross multiplication with the help of various examples.

In this chapter, we learn about positive, negative, and zero indices along with some laws for solving problems based on them. It also explains how to simplify an expression and solve an exponential equation.

This chapter teaches us about the product, quotient, and power laws of the logarithm. We also learn to expand an expression using the laws of the logarithm. Exercises with answers are given here for a better understanding of the concept.
