History of Roman Numerals

Roman numerals originated in ancient Rome and were used throughout Europe well into the Middle Ages. They use seven Latin letters — I, V, X, L, C, D and M — to represent numbers. The system uses both addition (III = 3) and subtraction (IV = 4, IX = 9) to form values.

Today, Roman numerals are used for clock faces, book chapters, movie sequels, Super Bowl numbers, monarchs (King Charles III), and the Olympic Games. They add a classical, timeless aesthetic that Arabic numerals cannot replicate.
