Integers  In mathematics, are numbers that can either be positive, negative, or even zero but can never be a fraction. Integers are very important and play a fundamental role in significant arithmetic operations such as addition, subtraction, multiplication, and division. Some of the examples of integers are; -5, -2, 0, 3, 9, but if you observe numbers like 5/4, -3/9, 29/2 are not integers because they are fractions. Even decimals and percentages cannot be denoted as integers. The symbol of integers is Z. The RD Sharma Solutions for Class 7 Maths Chapter 1 integers deal with various essential concepts of integers to explain the topics to the students. Those topics include four fundamental concepts. They are addition, subtraction, multiplication, and division of integers.

FAQs on RD Sharma Class 7 Solutions Chapter 1 - Integers (Ex 1.3) Exercise 1.3

1. What is an integer?

Whole Numbers that can be positive or negative but can be represented without any fractional component are defined as integers. Basically, any counting numbers 1,2….and numbers obtained from the addition, subtraction, and multiplication of these numbers form the set of integers. Components obtained from the division of the integers cannot always be integers because in some cases they result in fractional components. All the whole numbers and their negative values including zero in between comprise the set of integers. Any fraction, square root, or cube root which do not give whole numbers are not integers.

2. Where can I find RD Sharma Solutions for Class 7 Chapter 1?

RD Sharma Solutions for Class 7 Chapter 1 is available on Vedantu, where students can find revision notes, free PDF, and other resources to help make exam preparation easier. 

3. What is the importance of learning integers?

Integer is the basic concept on which the whole world of mathematics revolves. They help to calculate efficiently both positive and negative numbers in every area starting from day-to-day calculations of any field. It is even important to compute where the student stands in the class or what is the score of the student. How much more the student needs to score to top the class also needs integers. Almost everything in the real world depends on computation and the representation of integers. The concept of integers is so important that it should be started from early classes. We can even add integers of different signs making computation even easier.

4. How to make the learning of integers at the Class 7 level interesting?

 Integer is an easy chapter and can be made interesting in the following ways:

  • Learning integers with card games

  • Quizzes on integers can make the learning a fun

  • Referring to interactive books on integers

  • Integer maze which is basically a puzzle with a network of paths and even printable in google slides is another way to make the study of integers interesting

  • Online games where integers are randomly used also makes learning a fun

  • Practicing integers on whiteboards.

  • Solving addition and subtraction puzzles.

  • Visual graphic organizer for the students to learn the rules of adding and subtracting integers.

All these make the learning of integers interesting and easy to grasp.

5. What are the key points to note in integers at the Class 7 level?

The important points which can make the learning of integers easy are listed as follows:

  • Types of numbers in integers

  • Concept of Number line

  • Rules of integers: (i) Addition rule: If signs of two integers are the same add them and keep the sign. (ii) Subtraction rule: To subtract one integer from the other just add the opposite of one integer to the original integer. This will help in canceling double negatives where applicable. (iii) Multiplication rule: The product of two positive integers is positive, a product of two negative integers is positive, the product of one positive and one negative integer is negative. Division rule: Division two positive integers give positive integer, division between two negative integers gives one positive integer, a division between one positive and one negative integer gives negative integer.
