About Roman Numerals
Roman numerals originated in ancient Rome and remained the standard way of writing numbers throughout Europe for many centuries. The system uses combinations of letters from the Latin alphabet to signify values.
Key principles:
- I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000
- Numerals are written from largest to smallest, left to right
- When a smaller numeral appears before a larger numeral, it is subtracted (e.g., IV = 4, IX = 9)
- Only I, X, and C can be used as subtractive numerals
- A numeral can't be repeated more than 3 times in a row
