Let us discuss the sub-topics in detail.

12.1 Introduction:

Algebraic Expression is an essential topic for students. It will maths subject, which fundamental concepts are useful in further studies.

12.2 How are Expressions Formed?

Expressions are made up of terms. Terms are added to make an expression.

12.3 Terms of an Expression:

A term is a product of factors. Factors containing variables are known as algebraic factors. Each term is having coefficients.

12.4 Like and Unlike Terms:

Terms having the same algebraic factors are like terms otherwise they are unlike terms.

12.5 Monomials, Binomials, Trinomials and Polynomials:

The student will study the different expressions based on a number of terms. An expression with only one term is monomial. An expression that contains two unlike terms is binomial. An expression that contains three terms is trinomial.

12.6 Addition and Subtraction of Algebraic Expressions:

The student will study the methods to add and subtract two or more algebraic expressions. Different examples will help students to grasp the concept.

12.7 Finding the Value of an Expression:

Value of an algebraic expression depends on the values of the variables in the expression. When we wish to check whether a particular value of a variable satisfies a given equation or no we can put values of variables in the equation.

12.8 Using Algebraic Expressions – Formulas and Rules:

In mathematics using algebraic expressions, we can write the formula and rules effectively by using various terms. ### Download Toppr – Best Learning App for Class 5 to 12
