Roman Numerals

Roman numerals, the numeric system in ancient Rome, uses combinations of letters from the Latin alphabet to signify values. The numbers 1 to 10 can be expressed in Roman numerals as follows:

I, II, III, IV, V, VI, VII, VIII, IX, and X.

The Latin numerics system, commonly known as the Roman numeral system is decimal but not directly positional and does not include a zero. It is a cousin of the Etruscan numerals. Use of Roman numerals persisted after the decline of the Roman Empire. In the 14th century, Roman numerals were largely abandoned in favor of Arabic numerals; however, they are still used to this day for things such as numbered lists or outlines, clock faces, numbering of pages preceding the main body of a book, successive political leaders or people with identical names, chords in music, some copyright dates, and the numbering of certain annual events.
