What are Roman Numerals?

General Questions

Roman numerals are a system of numerical notation used in ancient Rome. They are based on the use of the letters of the alphabet, specifically: I, V, X, L, C, D, and M. These letters represent the values 1, 5, 10, 50, 100, 500, and 1,000 respectively.

In Roman numerals, numbers are represented by stringing these letters together, with the larger value letters being placed before the smaller value letters. For example, the number 11 would be represented as "XI" (10 + 1), and the number 39 would be represented as "XXXIX" (10 x 3 + 10 - 1).

Additionally, Roman numerals use subtractive notation in some cases, such as using "IV" to represent 4 (5 - 1) instead of "IIII" and "IX" to represent 9 (10 - 1) instead of "VIIII".

Roman numerals were widely used in the Roman Empire and were the standard system of numbering in Europe until the Middle Ages, when the Hindu-Arabic numeral system (used in the modern world) began to gain widespread acceptance. Today, Roman numerals are still used in some contexts such as clock faces, numbering of movie sequels, book chapters, and even as the numbering system for Super Bowl games.
