What sets XII apart
- Two Is
- XII doubles I. A third I is still allowed, and that is XIII, 13; after it the ones switch to subtraction.
- XI plus one I
- Coming from 11, XI, you only add another I.
- Twice 6
- 12 is twice 6 (VI), but writing VI twice does not work: VIVI is not valid. Letters are out of order: values must go from largest to smallest.
