Roman Numeral Rules
Basic Symbols
Roman numerals are based on seven symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).
Addition Rule
When a symbol appears after a larger (or equal) symbol, it is added. For example: VI = 5 + 1 = 6, XII = 10 + 1 + 1 = 12.
Subtraction Rule
When a symbol appears before a larger symbol, it is subtracted. For example: IV = 5 - 1 = 4, IX = 10 - 1 = 9.
Only these subtractions are allowed:
- I can be subtracted from V and X (e.g., IV = 4, IX = 9)
- X can be subtracted from L and C (e.g., XL = 40, XC = 90)
- C can be subtracted from D and M (e.g., CD = 400, CM = 900)
Repetition Rule
A symbol can be repeated up to three times in a row. For example: III = 3, XXX = 30, CCC = 300.
Symbols V, L, and D are never repeated.
