Algebraic Expressions

This topic discusses the terms variables and constants. We will also learn in detail the difference between variables and constants.

In this topic, the concept of terms of an expression is explained clearly with examples. Factors and coefficients are also discussed here.

This topic describes like and unlike terms. The terms which have the same algebraic factors are called like terms. On the other hand, the terms which have different algebraic factors are called unlike terms. It completely depends on the factors.

The different algebraic expressions are explained in this topic in detail. We will learn that an expression with only one term is called a monomial, an expression that contains two unlike terms is called a binomial, etc.

In this topic, we will learn how to perform the mathematical operations of addition and subtraction of algebraic expressions with solved examples.

This topic discusses how the value of an algebraic expression depends on the values of the variables forming the expression. These values can be found using formulas from geometry and from everyday mathematics explained using solved examples.

This topic provides the formulas for finding the perimeter and area of equilateral triangles, squares, pentagons and rectangles. It also explains the rules for solving number patterns, followed by an activity using matchsticks.
