About Roman Numerals

Basic Rules

• Roman numerals use 7 basic symbols: I(1), V(5), X(10), L(50), C(100), D(500), M(1000)
• The same symbol can appear at most three times (e.g., III=3, but 4 is IV not IIII)
• A smaller number before a larger means subtraction (IV=4, IX=9, XL=40, XC=90, CD=400, CM=900)
• A smaller number after a larger means addition (VI=6, LX=60, DC=600)
• Arranged left to right, largest to smallest

Common Examples

• 2024 = MMXXIV (M+M+X+X+IV = 1000+1000+10+10+4)
• 1987 = MCMLXXXVII (M+CM+L+X+X+X+V+I+I)
• 3999 = MMMCMXCIX (maximum standard Roman numeral)
