FAQs on NCERT Solutions for Class 6 Maths Chapter 2  Whole Numbers (Ex 2.2)
1. What are whole numbers? 

Ans. Whole numbers are a set of numbers that include all the natural numbers (positive integers) along with zero. They do not include any fractions or decimals. For example, 0, 1, 2, 3, 4, 5, etc., are all whole numbers.
2. How are whole numbers different from natural numbers? 

Ans. Whole numbers and natural numbers are similar, except that natural numbers do not include zero, while whole numbers include zero in addition to the natural numbers. So, while the set of natural numbers is {1, 2, 3, 4, 5, ...}, the set of whole numbers is {0, 1, 2, 3, 4, 5, ...}.
3. Can negative numbers be considered whole numbers? 

Ans. No, negative numbers cannot be considered whole numbers. Whole numbers only include nonnegative integers, which means they do not include any negative numbers. Negative numbers are part of a different set called integers.
4. How do we represent whole numbers on a number line? 

Ans. Whole numbers can be represented on a number line by marking the points corresponding to each whole number. The number line starts from zero and extends to the right, with each whole number represented by an equidistant point. For example, 0 is represented by the origin, 1 is represented by the first point to the right of zero, 2 is represented by the second point, and so on.
5. What are the properties of whole numbers? 

Ans. Whole numbers have several properties, including closure under addition and multiplication, commutativity, associativity, and distributivity. These properties allow us to perform operations like addition, subtraction, multiplication, and division on whole numbers and obtain meaningful results. Additionally, whole numbers also follow the property of order, where larger numbers are greater than smaller numbers.
