What Are Roman Numerals?

Roman numerals are a numbering system used in Ancient Rome that uses seven symbols from the Latin alphabet (I, V, X, L, C, D and M) to represent numerical values. Reading a Roman numeral depends on the position of its symbols: the general rule is to add the values, but if a symbol of lesser value comes before one of greater value, the former is subtracted from the latter (e.g., IV = 4, IX = 9). This system was widely used for almost two millennia and is still seen on clocks, in books, and on monuments.
