How LXXXVII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 87 separately and joining the pieces gives LXXXVII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Tens | 8 | 80 | LXXX |
| Ones | 7 | 7 | VII |
Reading it back, left to right:
- L = 50 → running total 50
- X = 10 → running total 60
- X = 10 → running total 70
- X = 10 → running total 80
- V = 5 → running total 85
- I = 1 → running total 86
- I = 1 → running total 87
The rules LXXXVII follows
- Largest to smallest. LXXXVII uses the symbols L, X, V and I (7 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 87 is a 4 or a 9, so LXXXVII 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.

- Volumes and sequels. Book volumes, conference editions, film sequels and anniversary events often carry a Roman numeral; edition LXXXVII would be the 87th.
