300 in Roman Numerals = CCC

Roman Numeral Rules Used

Roman numerals use seven symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). Numbers are formed by combining symbols and adding their values. When a smaller symbol appears before a larger one, it is subtracted (e.g., IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900).

To convert 300: start with the largest possible symbol and subtract its value, repeating until the remainder is zero. The result is CCC.
