📖 How Roman Numerals Work
Roman numerals use combinations of letters from the Latin alphabet to represent values. The system is based on adding and subtracting values.
Basic Rules
- Addition: When a smaller value follows a larger one, add them. VI = 5 + 1 = 6
- Subtraction: When a smaller value precedes a larger one, subtract. IV = 5 - 1 = 4
- Repetition: A numeral can be repeated up to 3 times. III = 3
- No Zero: Roman numerals have no symbol for zero
Common Examples
- 2024 = MMXXIV
- 1999 = MCMXCIX
- 500 = D
- 49 = XLIX
- 14 = XIV
