Algebra

This chapter introduces the concept of expansions. It highlights the expansions of various algebraic identities, including the square of a binomial and trinomial, etc. With the help of examples, we will learn how to expand the expressions.

This chapter focuses on the concept of factorisation. It explains how to factorise the numbers by taking out the common factors. It discusses the method of splitting the middle term. Factorisation by the sum or difference of two cubes is also given.

This chapter discusses the concept of simultaneous linear equations in two variables. It highlights the different methods used for solving linear equations. It also briefs us on the substitution, elimination, and cross-multiplication methods.

This chapter discusses the concept of indices or exponents. It briefs on the index of a number. It also highlights various laws of indices. Further, through examples, we will learn how to apply these laws to simplify the given expressions.

In this chapter, we will understand the concept of the logarithm. It explains different laws associated with logarithms. With the help of examples, it also describes how to convert logarithmic form to exponential form and vice versa.
