How Roman Numerals Work
Roman numerals follow simple placement rules:
Addition: When a smaller value comes after a larger one, you add. VI = 6 (5 + 1).
Subtraction: When a smaller value comes before a larger one, you subtract. IV = 4 (5 – 1).
Repetition: You can repeat a symbol up to three times. XXX = 30.
Our converter handles all these rules automatically.
Examples
- 2025 = MMXXV
