V 5
X 10
L 50
C 100
D 500
M 1000

How the Roman Number System Works

Roman numerals are formed using combinations of letters based on addition and subtraction rules:

  • Letters are added when placed after a larger value (VI = 6)
  • Letters are subtracted when placed before a larger value (IV = 4)
  • The same symbol is not repeated more than three times in a row

Because these rules can be confusing, a roman digit converter is the easiest way to avoid mistakes.
