The set of numbers that are used to count or to tally objects in a set.

We can also define the set of whole numbers as being the set of cardinals of finite sets.

### Symbols

- The set of whole numbers is noted as \(\mathbb{W}\).

\(\mathbb{W}\) = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, …} - The set of natural numbers is noted as: \(\mathbb{N}\)*.

\(\mathbb{N}\)* = {1, 2, 3, 4, 5, 6, 7, 8, 9, …}

### Properties

- The sequence of whole numbers is an infinite sequence.
- The number 0 is a whole number.
