RD Sharma Class 6 Solutions Chapter 4

Introduction to the Chapter

RD Sharma Class 6 Chapter 4 explores Operations on Whole Numbers and discusses natural numbers, predecessors and successors, number lines and addition, subtraction, multiplications of natural and whole numbers. Also, following the topics are numerous examples along with questions for a better understanding of the chapter. We also talk about how the addition of  0 and 1 help in differentiating between both natural and whole numbers and how we calculate the same on the number line. All such doubts are cleared through the exercises given after the chapter.


Operations on Whole numbers is an important chapter for building a strong base in understanding natural and whole numbers which often confuse the students even in the later classes. Natural numbers are what we use to count like 1,2,3… etc. When we add zero ahead of a collection of natural numbers, i.e., 0,1,2,3,...etc., they now become a collection of whole numbers. Although all natural numbers are whole numbers, not all whole numbers are natural numbers. Every natural and whole number has a predecessor and a successor except for 1 in the case of natural numbers and zero in whole numbers. We can calculate a successor by adding one to a number and the predecessor by subtracting one from the number. We use all these rules while making the number line. The starting point is marked as zero followed by the whole numbers in equal segments. Here, we can perform operations like addition, subtraction and multiplication. In addition, students should move towards the right of the table and for subtraction, move to the left. On dividing a whole/natural number with zero, it cannot be defined. The addition and multiplication of two numbers can be done in any order but it is not the same for subtraction and division.

FAQs on RD Sharma Class 6 Solutions Chapter 4 - Operations on Whole Numbers (Ex 4.3) Exercise 4.3

1. Is RD Sharma class 6 Maths the best resource that students should follow?

Teachers recommend RD Sharma Class 6 Maths because of the excellent question banks, the explanation of solutions and the various methods used to solve the problems. One of the best features of the book is that it gives enough scope to the students to analyse their strengths and weaknesses and also provides strategies to improve. If the students need more help, they can follow Vedantu for RD Sharma Class 6 Solutions Chapter 4- Operations on Whole numbers in downloadable PDF format for free.

2. How many exercises are present in RD Sharma Class 6 Chapter 4 - Operations on Whole Numbers?

There are a total of five exercises from 4.1 to 4.6. Objective type questions are also included in the question bank. Each of these exercises is related to the topics given in the chapter like the number line, addition, subtraction and multiplication of natural numbers and whole numbers (separately and mixed), etc. There are also some tricky questions asked like whether a rectangular number or a triangular number can be a square number or observing a pattern and filling the blanks. Links to the solutions of the question of other exercises of chapter 4 are - 

3. What is the difference between natural and whole numbers?

Natural numbers are those collections of numbers that can be counted by hand. For example 1, 2, 3, 4,....etc. are natural numbers in which 1 is the smallest number in the collection. 0, negative numbers, decimals and fractions are not considered natural numbers. Whole numbers include 0, natural numbers and positive integers as well except for decimals and fractions. Arithmetic operations can be performed on whole numbers like addition, subtraction, multiplication and division. 0 is the smallest whole number. 

4. How do we add or subtract whole numbers on the number line?

A number line includes numbers that are placed in equal segments with the starting point being 0. The rest of the numbers continue and extend towards the right (for positive integers) and towards the left (for negative integers). Calculations on the number line are done to compare the predecessors and the successors as well as to perform Mathematical operations like addition, subtraction and multiplication. In addition, students must calculate from the right of the integers in question and to subtract, move towards the left of the number line.
