How XXII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 22 separately and joining the pieces gives XXII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Tens | 2 | 20 | XX |
| Ones | 2 | 2 | II |
Reading it back, left to right:
- X = 10 → running total 10
- X = 10 → running total 20
- I = 1 → running total 21
- I = 1 → running total 22
The rules XXII follows
- Largest to smallest. XXII uses the symbols 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 22 is a 4 or a 9, so XXII is purely additive: just add the symbol values.
- Repetition. XX repeats X two 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 XXII
- The U.S. Constitution. Amendments are often cited in Roman numerals: Amendment XXII limits presidents to two elected terms (ratified in 1951).
- The modern Summer Games. They are officially numbered by Olympiad; the Games of the XXII Olympiad belong to 1980: Moscow.
- Championship games. Pro football numbers its championship game with Roman numerals, starting from game I in January 1967. Game XXII was played in early 1988.
- Volumes and sequels. Book volumes, conference editions, film sequels and anniversary events often carry a Roman numeral; edition XXII would be the 22nd.
