XIV Roman Numeral: What Number Is XIV?
Numbers and numerals are detected as you type. Enter copies, Alt+S swaps.
XIV is 14 (fourteen). I stands before a larger symbol and is subtracted; everything else is added: 10 − 1 + 5 = 14.
Reading XIV letter by letter
XIV splits by place into X (ten) and IV (four).
| Letter | Value | Step | Total |
|---|---|---|---|
| X | 10 | start | 10 |
| I | 1 | subtract (V is larger) | 9 |
| V | 5 | add, closing IV | 14 |
Why XIV is valid
- V appears once
- Never doubled, never before a larger letter.
- The pair IV
- An allowed pair, and the only place where the values rise.
Easy to confuse with XIV
XVI, the same letters swapped, is 16 (XVI roman numeral).
XIIII is the additive form; the standard form of 14 is XIV. Wikipedia
