ABOUT ROMAN NUMERALS

Roman numerals use Latin letters (I, V, X, L, C, D, M) to represent numbers. Though the decimal system has replaced them in most practical applications, Roman numerals remain common on clock faces, book chapter numbering, movie sequels, Super Bowl numbering, building cornerstones, and formal event programmes.

Roman numerals represent integers from 1 (I) to 3,999 (MMMCMXCIX). The system uses subtractive notation — IV (4) is I before V, not IIII. Roman numerals are part of the maths curriculum in Indian schools (Class 5-6).
