How it works
Roman numerals combine seven symbols — I (1), V (5), X (10), L (50), C (100), D (500) and M (1,000). Write each place value of the number separately, from thousands down to ones, and join the results. Six subtractive pairs replace four repeated symbols: IV (4), IX (9), XL (40), XC (90), CD (400) and CM (900). No symbol appears more than three times in a row.
