Roman numerals use seven symbols to represent numbers. They are still widely used for clock faces, book chapters, movie sequels, and formal numbering.

Roman Numeral Symbols:

  • I = 1
  • V = 5
  • X = 10
  • L = 50
  • C = 100
  • D = 500
  • M = 1,000

Subtractive Notation:

Roman numerals use subtractive notation to avoid four consecutive identical symbols:

  • IV = 4 (5 - 1)
  • IX = 9 (10 - 1)
  • XL = 40 (50 - 10)
  • XC = 90 (100 - 10)
  • CD = 400 (500 - 100)
  • CM = 900 (1000 - 100)

Examples:

  • 2024 = MMXXIV
  • 1999 = MCMXCIX
  • 1776 = MDCCLXXVI

Standard Roman numerals can represent values from 1 to 3,999. Numbers 4,000 and above historically required overlines or other notation.
