Understanding Roman Numerals

Roman numerals use seven letters to represent numbers:

  • I = 1 - The smallest unit
  • V = 5 - Five
  • X = 10 - Ten
  • L = 50 - Fifty
  • C = 100 - One hundred
  • D = 500 - Five hundred
  • M = 1000 - One thousand

Roman numerals follow specific rules:

  • When a smaller numeral appears before a larger one, it's subtracted (e.g., IV = 4, IX = 9)
  • When a smaller numeral appears after a larger one, it's added (e.g., VI = 6, XI = 11)
  • The same numeral cannot appear more than three times in a row (e.g., III = 3, but IIII is invalid)
  • Standard combinations include: IV (4), IX (9), XL (40), XC (90), CD (400), CM (900)
