16 in Roman numerals is XVI. Split 16 by place value: 10 is X and 6 is VI, and X + VI joins into XVI. All its letters are added: 10 + 5 + 1 = 16. In lowercase it is xvi, and the number is sixteen.
How XVI is built
tens10 = 10 → X
10 is a single X.
ones6 = 5 + 1 → VI
6 is 5 plus 1, so V is followed by I: VI.
What sets XVI apart
- No letter repeats
- Each of the three letters in XVI appears once.
- XV plus one I
- Coming from 15, XV, you only add another I.
- Twice 8
- 16 is twice 8 (VIII), but writing VIII twice does not work: VIIIVIII is not valid. Only one I can be subtracted from a larger letter.
