DCCXL

DCCXL is the Roman numeral for the number 740. It is formed by the symbols D (500), CC (200), and XL (40). The subtractive pair XL indicates 40, since X placed before L reduces 50 by 10. Adding these values yields 500 + 200 + 40 = 740.

Roman numerals are a non-positional numeral system that originated in ancient Rome and continued to be used, in various forms, for dates and enumerations. DCCXL would be used in contexts that require Roman numerals to represent the quantity 740, such as on inscriptions, clock faces, or in bibliographic references and lists.

In historical dating, DCCXL can denote the year 740 in the Julian calendar, commonly written as AD 740 or 740 CE depending on the dating convention in use. Beyond dating, the numeral may also label a position in a sequence, such as the 740th item, edition, or section, where Roman numerals are preferred for stylistic or traditional reasons.

The use of DCCXL, like other Roman numerals, is largely specialized in modern times, typically appearing in formal inscriptions, certain academic or historical writings, and decorative or retro design contexts. It remains part of the broader system of Roman numerals and their methods of subtractive notation.
