Students have already come across simple algebraic expressions like x + 3, y – 5, 4x + 5, 10y – 5 and so on. In Class VI, students have seen how these expressions are useful in formulating puzzles and problems. They have also observed examples of several expressions in the chapter on Simple Equations. Expressions are a central concept in algebra. NCERT Grade 7 Mathematics Chapter 12, Algebraic Expressions is devoted to algebraic expressions. This chapter will deal with how algebraic expressions are formed, how they can be combined, how we can find their values and how they can be used.
Introduction to Algebraic Expressions, How Are Expressions Formed? Terms Of An Expression, Like And Unlike Terms, Monomials, Binomials, Trinomials And Polynomials, Addition And Subtraction Of Algebraic Expressions, Finding The Value Of An Expression, Using Algebraic Expressions – Formulas and Rules are the topics covered in this chapter. Summary, Do Yourself Activities and Group exercises help the students to dive into the world of Algebraic Expressions with a throttle and master the topic.
Pictorial representation and graphical representation makes the chapter more interactive and clears the concepts in a better and comprehensive manner. This chapter will help the students to strengthen their foundation on Algebraic Expressions to deal with further complex topics meritoriously.A foundation base for future complex topics, NCERT Grade 7 Mathematics Chapter 12, Algebraic Expressions is fun and easy to understand.
