The set of basic symbols in the Roman system of writing numerals

The major set of symbols on which the rest of the Roman numberals were built:

  • 1 = I (one)
  • 5 = V (five)
  • 10 = X (ten)
  • 50 = L (fifty)
  • 100 = C (one hundred)
  • 500 = D (five hundred)
  • 1,000 = M (one thousand)
  • 5,000 = (V) (five thousand) *
  • 10,000 = (X) (ten thousand) *
  • 50,000 = (L) (fifty thousand) *
  • 100,000 = (C) (one hundred thousand ) *
  • 500,000 = (D) (five hundred thousand) *
  • 1,000,000 = (M) (one million) *

* Number was also written with a bar above or between two vertical bars. We prefer writing in brackets because it is more accessible to computer users and also removes any ambiguity between a vertical bar | and a Roman numeral I.

* Romans did not use numbers higher than 3999 right from the beginning, they were having no representation for numbers like 5,000, 10,000, 50,000, 100,000, 500,000, 1,000,000. These were later added and for them various different notations were used, not necessarily the ones above. Thus, initially, the maximum number that could be written with Roman numerals was: MMMCMXCIX (3999).
