1800-102-2727An algebraic expression is an expression of the variable with or without exponents. In this chapter, you will learn about the methods of solving algebraic expression involving one or two variables. In Ex 12.1, you will learn about how expressions are formed, terms of an expression, like and unlike terms, monomials, binomials, trinomials and polynomials. There are two types of terms in algebra: constant and variables. Constant is a term with a fixed numerical value, and a variable is a symbol that takes on a various numerical value. The part of the expression that is formed separately and then added are called terms.
The combination of constants and variables forms an expression. A monomial has one term, binomial has two terms, and a binomial has three terms. In Ex 12.2, students will learn about addition and subtraction of like terms and general algebraic expressions. In Ex 12.3, students will know how to find the value of an algebraic expression's expression. In Ex 12.4, you will learn about formulas and rules used in this chapter.
