Before we begin the chapter on Integers, we will revise the concepts of Whole numbers and Natural numbers in this segment.
What are Natural numbers?
- The numbers that are used for counting are called Natural numbers.
- Natural numbers include 1, 2, 3, 4 and so on.
- As these numbers are used for counting of objects, they are also known as Counting numbers.
What are Whole numbers?
- All-natural numbers and zero are Whole numbers.
- Whole numbers include 0, 1, 2, 3, 4, and so on.
- Thus, the set of whole numbers will consist of natural numbers and a zero.
Why do we use zero?
Zero is not a natural number as it cannot be used to count any object.
Zero is an important number. For example,
If there is a box of empty chocolates, it means the box contains 0 chocolates. Similarly, in the case of a thermometer, sometimes the temperature is close to 0\[0^{\circ} C \].
