CMXXIV

CMXXIV is the Roman numeral representation of the integer 924. In standard Roman numeral notation, CM stands for 900, XX for 20, and IV for 4, and together they sum to 924.

The numeral employs subtractive notation: a smaller numeral placed before a larger one indicates subtraction. CM uses C (100) before M (1000) to subtract 100 from 1000, yielding 900. XX adds 20, IV adds 4. The rules require that subtractive pairs be limited to certain combinations, such as I before V or X, X before L or C, and C before D or M.

Historical and practical use: Roman numerals were widely used in the ancient and medieval worlds for inscriptions, tallies, dates, and numbering. CMXXIV would typically appear in contexts requiring compact, non-arabic numerals, such as year notation on inscriptions or manuscripts; for example, a year 924 CE could be written as CMXXIV in some contexts, though in most modern writing, years are expressed with Arabic numerals.

Modern usage and significance: As a mere representation of the number 924, CMXXIV has no independent meaning beyond its numeric value. It may appear in puzzles, typographic designs, clock faces, or as part of stylized dating. It is primarily of interest to students of numerals and historical notation.
