MMCMXVIII

MMCMXVIII is the Roman numeral for the number 2918. It is formed from the symbols MM (2000), CM (900), and XVIII (18), adding up to 2000 + 900 + 18 = 2918. The CM segment illustrates subtractive notation, where a smaller value placed before a larger one reduces the total by that amount (100 before 1000 yields 900).

Roman numerals originated in ancient Rome and remained in use for various purposes through the medieval period and beyond. In modern practice they appear in dating events, labeling monarchs and popes, numbering chapters or outlines, and in decorative or ceremonial contexts such as clocks, film titles, or edition numbering. For general counting and arithmetic, Arabic numerals are far more common today, but Roman numerals continue to be used where a classical or formal appearance is desired.

As a designation, MMCMXVIII would denote the number 2918 when interpreted in its standard decimal value. If used as a year designation, it would correspond to AD 2918 in the Gregorian calendar. The form demonstrates the typical rules of Roman numeral construction, including additive sequences like MM and XVIII and subtractive pairs like CM, within a compact four-symbol presentation.
