What are Whole Numbers?

 

 

We saw that numbers are used to count the things. We use symbols to write numbers. Those

symbols are called ‘digits’. We use ten symbols-   0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

As we use ten symbols to write numbers, our system of writing numbers is called the ‘Decimal

system’. In this system, the value of a numeral is told by its place in the number. We have seen

this in ‘Place value of digit’.

 

 

 

Zero is also considered as a number and zero is added to the group of natural numbers and a

new group starting from zero is formed, that is  0, 1, 2, 3, 4, 5, 6, 7, 8, 9….

This set is called as the ‘set of whole numbers‘ .

The symbol for the set of whole numbers is ‘W‘.

We can write it as;

W = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9…..}

That is, the set of whole numbers starts from 0.

We can say that-

1. The value of whole number is increased from left to right.

2. If we go further from left to right, we get more numbers. There are innumerable

 numbers. There is no end to these numbers. So like natural numbers, we cannot tell the

 biggest whole number.

W = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9…..}
