How LXXI is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 71 separately and joining the pieces gives LXXI:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Tens | 7 | 70 | LXX |
| Ones | 1 | 1 | I |
Reading it back, left to right:
- L = 50 → running total 50
- X = 10 → running total 60
- X = 10 → running total 70
- I = 1 → running total 71
The rules LXXI follows
- Largest to smallest. LXXI uses the symbols L, X and I (4 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 71 is a 4 or a 9, so LXXI is purely additive: just add the symbol values.
- Repetition. XX repeats X 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 LXXI
- Championship games. Pro football numbers its championship game with Roman numerals, starting from game I in January 1967. Game LXXI falls in early 2037.
- Volumes and sequels. Book volumes, conference editions, film sequels and anniversary events often carry a Roman numeral; edition LXXI would be the 71st.
