14 in Roman Numerals
Numbers and numerals are detected as you type. Enter copies, Alt+S swaps.
14 in Roman numerals is XIV. Split 14 by place value: 10 is X and 4 is IV, and X + IV joins into XIV. XIIII is not standard: it puts four Is in a row, one more than the rules allow, so the ones are written IV. In lowercase it is xiv, and the number is fourteen.
How XIV is built
tens10 = 10 → X
10 is a single X.
ones4 = 5 − 1 → IV
4 is 5 minus 1, so I goes before V: IV.
What sets XIV apart
- Ends in IV
- Only the final IV subtracts. The X in front is a plain 10, and IV adds 4 to it.
- No letter repeats
- Each of the three letters in XIV appears once.
- One letter shorter
- From 13 to 14 only the ones change, III becoming IV, and the numeral loses one letter.
- Twice 7
- 14 is twice 7 (VII), but writing VII twice does not work: VIIVII is not valid. Only one I can be subtracted from a larger letter.
