CCXLV

CCXLV is the Roman numeral for the number 245. It is formed by combining CC (two hundreds), XL (forty in subtractive notation), and V (five). Specifically, CC equals 200, XL equals 40, and V equals 5; adding these values yields 245. This construction follows standard Roman numeral rules, where smaller numerals placed before larger ones indicate subtraction (XL = 40) and those placed after are additive (CC and V).

In historical contexts, CCXLV may appear on inscriptions, manuscripts, or monuments to denote the year 245 in a given calendar (for example, 245 CE or 245 BCE depending on context). In modern usage, Roman numerals like CCXLV are sometimes employed for stylistic or traditional purposes, such as chapter numbering, outlines, or to designate events and monarchs in a formal or ceremonial setting.

Outside numeric usage, CCXLV can also function as a string that serves as an identifier, model number, or catalog code, with its meaning determined entirely by the surrounding context. As a Roman numeral, however, CCXLV is unambiguous and universally understood to represent 245. See also Roman numerals and the number 245.
