NCERT Solutions for Class 7 Maths Chapter 12: Important Topics

In this chapter, students will mainly study how to form algebraic expressions, combine them, find their values and use them. A variable can take various values. Its value is not fixed. On the other hand, a constant has a fixed value. When they both are combined, we get an algebraic expression. For this, we use the addition, subtraction, multiplication and division operations that students will learn in this chapter.
