**NCERT Solutions for Class 7 Maths**

Class 7 Maths Chapter 12 talks about algebraic expressions in detail. Embibe provides over 2000+ sample questions for the sub-topics included in Chapter 12. Students should solve the in-text questions provided by Embibe to learn the topics well. This article provides the NCERT Solutions for Class 7 Chapter 12 Maths and 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.

The NCERT Solutions for **Class 7 Maths Chapter 12** will help students learn the 27 concepts taught in this chapter. Students can practice hundreds of sample questions based on each concept at Embibe for free and score good marks in their exams.

Below are some key points to remember in this exercise:

- Literal numbers or literals are the letters used to represent numbers.
- The literal and the combinations of literal numbers and numbers obey all the rules (and signs) of addition, subtraction, multiplication, and division of numbers, along with the properties of these operations.
- A constant is a symbol having a fixed numerical value.
- A variable is a symbol having various numerical values.
- An algebraic expression is the combination of constants and variables connected by the signs of fundamental operations of addition, subtraction, multiplication and division.
- Terms of the expression are the various parts of an algebraic expression which are separated by the signs of ‘+’ or ‘−‘.
