Answer: A data value that includes all-natural numbers, as well as 0, is called a whole number. They are decimals, fractions, and negative values that are not included in real figures. However, the whole numbers consist of counting natural numbers as well but with a minute distinction.
For example,
A set of numbers such as starting from 1 as 12345678 is called a natural number and not a whole number as it does not contain 0.
However, set 012345678 is a set of whole numbers as well as natural numbers.
The point to remember is that all whole numbers are natural numbers. However, if we see it the other way all-natural numbers are not whole numbers.
