FAQs on NCERT Textbook- Numbers - Mathematics for Class 1: NCERT

1. What are numbers and why are they important?
Ans. Numbers are mathematical entities used for counting, measuring, and calculating. They are important because they form the foundation of mathematics and are used in various real-life situations such as calculating quantities, measuring distances, and solving complex mathematical problems.
2. What is the difference between natural numbers and whole numbers?
Ans. Natural numbers are the set of positive integers starting from 1 and going up to infinity. Whole numbers, on the other hand, include zero along with the set of natural numbers. In other words, whole numbers are obtained by adding zero to the set of natural numbers.
3. How are rational numbers different from irrational numbers?
Ans. Rational numbers are numbers that can be expressed as a fraction, where both the numerator and denominator are integers. Irrational numbers, on the other hand, cannot be expressed as a fraction and their decimal representation goes on forever without repeating. Examples of irrational numbers include square roots of non-perfect squares such as √2 or π.
4. What are prime numbers and how are they identified?
Ans. Prime numbers are numbers that have only two factors - 1 and the number itself. They cannot be divided evenly by any other number. To identify whether a number is prime or not, we can check if it is divisible by any number other than 1 and itself. If it is not divisible, then it is a prime number.
5. How are real numbers different from imaginary numbers?
Ans. Real numbers are the set of all rational and irrational numbers, which include integers, fractions, decimals, and square roots of non-perfect squares. They can be represented on a number line. Imaginary numbers, on the other hand, are numbers that involve the imaginary unit "i," which is defined as the square root of -1. They are used in complex numbers and cannot be represented on a number line.
