Roman numerals use seven letters, each with a fixed value: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, and M = 1000. Numbers are formed by combining these symbols and adding their values, working from the largest to the smallest.
When a smaller symbol appears before a larger one, it is subtracted instead of added — this is the subtractive rule. For example, IV is 4 (5 − 1) and IX is 9 (10 − 1). The same idea gives XL (40), XC (90), CD (400), and CM (900). The same symbol is never repeated more than three times in a row.
