MCDXCIX

MCDXCIX is the Roman numeral for the number 1499. It is formed by M (1000) + CD (400) + XC (90) + IX (9). The subtractive pairs CD, XC, and IX are part of the standard Roman numeral convention, allowing a smaller value to precede a larger one to indicate subtraction.

In practical use, 1499 appears as a year designation and in enumerations requiring Roman numerals. For example, 1499 AD would be written as MCDXCIX. It is one less than 1500, which is written MD in Roman numerals. The numeral demonstrates the compact way Roman numerals encode four-digit numbers by combining thousands (M) with subtractive groups for hundreds, tens, and units.
