MCMXCIX
MCMXCIX is the Roman numeral for the number 1999. It is composed of the symbols M (1000), CM (900), XC (90), and IX (9), arranged in descending order. The use of subtractive notation—placing smaller values before larger ones (CM, XC, IX)—is a standard feature of Roman numerals. Therefore MCMXCIX equals 1000 + 900 + 90 + 9, totaling 1999.
