A Roman numeral is read like this:
Numeral I V X L C D M
Value 1 5 10 50 100 500 1000
  • It is read from left to right from the biggest numeral to the lowest*, adding up:
    *: not entirely true, see subtractions below
    • DCLVII = DCLVII = 500 + 100 + 50 + 5 + 1 + 1 = 657
  • A subtraction is done by writing one smaller numeral before a big one:
    • 9 could be written VIIII, or IX = 1 and 10 = 10 - 1 = 9 / but IIX for 8 doesn't exist, only VIII
  • The same numeral can be put together multiple times, but usually (there is no standard, but the shorter version is usually preferred) up to the point where it can be subtracted from the bigger numeral above the used one (subtraction still done with only one numeral):
    • IIII = IV, CCCC = CD

Now let's see if you can translate this one: MCMLXXXV. Tip: where it all started ;-) MCMLXXXII for the purists!
