How LXIII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 63 separately and joining the pieces gives LXIII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Tens | 6 | 60 | LX |
| Ones | 3 | 3 | III |
Reading it back, left to right:
- L = 50 → running total 50
- X = 10 → running total 60
- I = 1 → running total 61
- I = 1 → running total 62
- I = 1 → running total 63
The rules LXIII follows
- Largest to smallest. LXIII uses the symbols L, X and I (5 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 63 is a 4 or a 9, so LXIII is purely additive: just add the symbol values.
- Repetition. III repeats I three 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 LXIII
- Championship games. Pro football numbers its championship game with Roman numerals, starting from game I in January 1967. Game LXIII falls in early 2029.
- Volumes and sequels. Book volumes, conference editions, film sequels and anniversary events often carry a Roman numeral; edition LXIII would be the 63rd.
