### What are Natural Numbers?

The **natural numbers** (i.e. **counting numbers**) are **numbers** which are used for **counting** and ordering. They can be expressed mathematically as: ℕ = { **1**, 2, 3, 4, 5, 6, 7, 8, 9, **10**, 11, 12, … } .

Some mathematicians consider 0 to be a **natural number**.
