FAQs on Understanding Natural Numbers, whole Numbers and Integers Video Lecture - Mathematics (Maths) Class 8

1. What are natural numbers?
Ans. Natural numbers are counting numbers that start from 1 and go up to infinity, such as 1, 2, 3, 4, 5, and so on.
2. What is the difference between whole numbers and natural numbers?
Ans. The main difference between whole numbers and natural numbers is that whole numbers include zero (0) while natural numbers do not. For example, the set of whole numbers is {0, 1, 2, 3, 4, 5, …}, while the set of natural numbers is {1, 2, 3, 4, 5, …}.
3. What are integers?
Ans. Integers are a set of numbers that includes whole numbers and their negatives, as well as zero. For example, the set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...}.
4. Can a natural number be negative?
Ans. No, natural numbers cannot be negative. Natural numbers are defined as counting numbers that start from 1 and go up to infinity, and do not include zero or negative numbers.
5. What is the relationship between natural numbers, whole numbers, and integers?
Ans. Natural numbers are a subset of whole numbers, and whole numbers are a subset of integers. In other words, every natural number is a whole number, and every whole number is an integer.
