DCCLXV

DCCLXV is the Roman numeral used to denote the number 765. In the system of Roman numerals, D represents 500, C represents 100, L represents 50, X represents 10, and V represents 5. When these values are added in the order given by D, C, C, L, X, and V, the total is 765 (500 + 100 + 100 + 50 + 10 + 5). The notation is additive and does not require subtractive notation for this particular combination.

DCCLXV may be encountered in historical texts, inscriptions, or modern documents that adopt Roman numerals for stylistic or formal reasons. It can appear in year designations such as 765 CE, in sequence numbering, or as part of a catalog or edition identifier where Roman numerals are preferred.

For clarity, 665 is written as DCLXV, not DCCLXV, so the presence or absence of the extra C changes the value. The use of DCCLXV is thus a straightforward application of the basic Roman numerals without subtractive notation.
