RS AggarwalSolutions for Class 6 Maths Chapter 8 Algebraic Expressions
RS Aggarwal Solutions for Class 6 Chapter 8 “Algebraic-Expressions”, algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). For example, 6x – 4, where x is the variable whose value is unknown, 6 is known as the coefficient of x and 4 is the constant term having a definite value. There are five types of algebraic expressions.
(i) Monomials – expression having one term known as monomials
(ii) Binomials – expression having two terms known as binomials
(iii) Trinomials – expression having three terms known as trinomials
(iv) Quadrinomials – expression having four terms known as quadrinomials
(v) Polynomials – expression having two or more terms known as polynomials
Algebraic Expressions are used in cooking, business management, sports, logical thinking.
Here, students use four fundamental operations such as addition, subtraction, multiplication and division on specific numbers and obtain number expressions. Key topics discussed here are operations on literals and numbers, algebraic expressions types namely monomial, binomial, trinomial, quadrinomials, polynomials, operations on algebraic expressions and use of grouping symbols.
