14. Roman numerals The Roman numeral system was used during the Roman empire. Does not include a zero. They are in use to this day in applications 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, and the numbering of certain annual events. The numbers 1 to 10 can be expressed in Roman numerals as follows: I, II, III, IV, V, VI, VII, VIII, IX, and X
