Additional information about Roman numerals: Roman numerals are a numeral system used in Europe before the introduction of Arabic numerals (actually Indian numerals), and are rarely used today. Their origin is later than the numerals in Chinese oracle bone script and even later than the decimal system of the Egyptians. Roman numerals have the following seven basic symbols: I (1), V (5), X (10), L (50), C (100), D (500), M (1000). Roman numerals differ from decimal numerals in that they have no symbol for zero and are not positional. A line drawn above a numeral indicates that the numeral's value is multiplied by 1000.
