Roman numerals are a numeral system originating from ancient Rome. They use combinations of letters from the Latin alphabet: I, V, X, L, C, D, and M. Each letter represents a specific value, such as I for 1, V for 5, and X for 10. Roman numerals are often used for numbering chapters, clock faces, and events like the Super Bowl. This system operates on additive and subtractive principles. For example, II represents 2 (1 + 1), while IV represents 4 (5 - 1). Although less common in modern mathematics, Roman numerals remain a cultural symbol and are still used in various contexts today.
