##### About 7 Maths Chapter 12

In 7 Maths Chapter 12 Algebraic Expressions, the questions based on mainly algebraic identities and it applications. In this chapter we will study about a variable and a constant. A variable can take various values. Its value is not fixed. On the other hand, a constant has a fixed value. Examples of constants are: 4, 20, –127, etc. Before discussing the algebraic expression, we should know about the terms, coefficients, etc.

###### Basic Terms about Algebraic Expressions

*Term*: The parts of algebraic expressions which are formed separately and then added for form an algebraic expressions. Such parts of an expression which are formed separately first and then added are known as terms.*Coefficient*: The factors of the terms may be numerical and the others algebraic. The numerical factor is said to be

the numerical coefficient or simply the coefficient of the term.

In this chapter we will learn the addition or subtractions of expression on the basis of like terms or unlike terms. Terms like monomial, binomial, trinomial or any polynomial. Finding the value of an expression given in this chapter will help you in later classes to study functions of variables.
