How XXXVII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 37 separately and joining the pieces gives XXXVII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Tens | 3 | 30 | XXX |
| Ones | 7 | 7 | VII |
Reading it back, left to right:
- X = 10 → running total 10
- X = 10 → running total 20
- X = 10 → running total 30
- V = 5 → running total 35
- I = 1 → running total 36
- I = 1 → running total 37
The rules XXXVII follows
- Largest to smallest. XXXVII uses the symbols X, V and I (6 characters in all), and the values never increase from left to right except inside a subtractive pair.
- No subtraction needed. None of the digits of 37 is a 4 or a 9, so XXXVII is purely additive: just add the symbol values.
- Repetition. XXX repeats X three times and II repeats I two times. I, X, C and M may repeat up to three times in a row; V, L and D never repeat.
Where you will see XXXVII
- Championship games. Pro football numbers its championship game with Roman numerals, starting from game I in January 1967. Game XXXVII was played in early 2003.
- Volumes and sequels. Book volumes, conference editions, film sequels and anniversary events often carry a Roman numeral; edition XXXVII would be the 37th.
