Some of the topics which have been discussed in this chapter are:

What are Expressions?

Terms, Factors and Coefficients

Monomials, Binomials and Polynomials

Like and Unlike Terms

Addition and Subtraction of Algebraic Expressions

Multiplication of Algebraic Expressions: Introduction

Multiplying a Monomial by a Monomial

2. Give some real-life use of Algebraic Expressions.

There are several instances in real life where we use algebraic expressions. After studying the chapter we will be able to use the concepts to solve real-life problems.

We can use these in real-life situations: such as, in calculating the area of a rectangle, of which the sides are represented as expressions.

There are many other applications of the concepts of the chapter Algebraic Expressions and Identities which students will be able to appreciate after studying the chapter.

3. What are Expressions?

In the Chapter algebraic expressions and identities, one of the first topics we come across is expressions.

An expression built up from constants and variables connected with algebraic operations. Expressions are made up of terms.

They can be further illustrated with the help of examples.

For example, 7x² − 8xy + c is an algebraic expression. Another such expression could be, 17x+ 7y.

Thus, this concludes the definition of expressions.
