MMMCXCVIII

MMMCXCVIII is a Roman numeral. In the modern Arabic numeral system, MMMCХCVIII translates to 3998. The Roman numeral system uses letters to represent numbers. M represents 1000, C represents 100, X represents 10, V represents 5, and I represents 1. When a smaller numeral follows a larger numeral, their values are added. Therefore, MMM represents 3000 (1000 + 1000 + 1000), XC represents 90 (100 - 10), and VIII represents 8 (5 + 1 + 1 + 1). Combining these segments gives 3000 + 90 + 8, resulting in 3998. The system, while historically significant, is not commonly used for everyday arithmetic due to its complexity compared to the positional Hindu-Arabic numeral system. Roman numerals are still found on clocks, in monarchical numbering (e.g., Queen Elizabeth II), and for specific legal or contractual references.
