How XXVII is built

Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 27 separately and joining the pieces gives XXVII:

Tens220XX
Ones77VII

Reading it back, left to right:

  • X = 10 → running total 10
  • X = 10 → running total 20
  • V = 5 → running total 25
  • I = 1 → running total 26
  • I = 1 → running total 27

The rules XXVII follows

  • Largest to smallest. XXVII uses the symbols X, V 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 27 is a 4 or a 9, so XXVII 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 XXVII

  • The U.S. Constitution. Amendments are often cited in Roman numerals: Amendment XXVII delays congressional pay changes until after the next election (ratified in 1992).
  • The modern Summer Games. They are officially numbered by Olympiad; the Games of the XXVII Olympiad belong to 2000: Sydney.
  • Championship games. Pro football numbers its championship game with Roman numerals, starting from game I in January 1967. Game XXVII was played in early 1993.
  • Volumes and sequels. Book volumes, conference editions, film sequels and anniversary events often carry a Roman numeral; edition XXVII would be the 27th.
