### 12 (twelve)

One of the most widely used numbers is 12. You can also call it a *dozen*.

##### Explanation

We all know that a year has 12 months. On a clock 12 hours are shown. There were 12 apostles.

*Is this all coincidence?*

Of course not. A dozen (12) or a gros (144) make really sense. Just look at (2 × 12 = 24) or (5 × 12 = 60) and (12 × 12 = 144).

The numeral system in which you calculate makes no difference, you can divide the number 12 in many ways, and that is so important.
