Understand the Concept of Whole Numbers through the Concept of Natural Numbers
Can you say what counting numbers are?
The numbers that we use for counting are called counting numbers. They start with 1. They are 1, 2, 3, 4 …. . These counting numbers are also called Natural Numbers. Therefore, we can define the natural numbers as follows:
“The collection of all counting numbers is known as Natural Numbers.”
What will we obtain, if we subtract 1 from 1?
If we subtract 1 from 1, then we obtain
1 − 1 = 0
The number 0 (zero) with all the natural numbers form a system of numbers, which is called Whole Numbers. This means whole numbers are a set of numbers starting from 0 i.e., 0, 1, 2 … and this can be defined as follows:
|“If zero is added to the collection of natural numbers, then we obtain the collection of whole numbers, or in other words, we can say that all natural numbers along with zero are called whole numbers.”|
Remember: All natural numbers are whole numbers, but all whole numbers are not natural numbers.
Think of any big number, say 20958340. We can write this number using symbols 0, 2, 3, 4, 5, 8 and 9.
Similarly, we can write a natural number using 10 symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Each of such…
