How Roman Numerals Work
Roman numerals use seven symbols (I, V, X, L, C, D, M) combined with additive and subtractive rules. When a smaller numeral appears before a larger one, it's subtracted (e.g., IV = 4). When it appears after, it's added (e.g., VI = 6). This converter handles both directions for any number between 1 and 3999.
