MMMCCCLXV

MMMCCCLXV is a Roman numeral that represents the number 3365 in the Arabic numeral system. It uses the symbols M (1000), C (100), L (50), X (10), and V (5) in a additive sequence.

The value is obtained by summing its parts: MMM equals 3000, CCC equals 300, L equals 50, and XV equals 15. Together these add to 3365. The numeral does not employ subtractive notation, such as IV for 4 or IX for 9, but rather stacks values in descending order to produce the total.

In the common modern convention for numbers up to 3999, MMMCCCLXV is a valid representation because it stays within the thousands range and does not require overlines or alternative forms. The use of three Ms indicates the thousands component, followed by hundreds, tens, and units. While ancient inscriptions sometimes varied in style, the standard form for 3365 in contemporary usage aligns with this additive construction.

Potential uses of MMMCCCLXV include denoting a year in historical fiction or a catalogue or model number in documentation. It can also serve as an example in explanations of Roman numeral notation, illustrating how larger values are built from repeating symbols without resorting to subtractive pairs.
