MMMCMXLVI

MMMCMXLVI is a Roman numeral representing the integer 3946. It is formed by the symbols M, CM, XL, and VI: three Ms (1000 each), followed by CM (900), XL (40), and VI (6). In this notation, larger values are placed before smaller ones, with subtractive pairs like CM for 900 and XL for 40 used to represent those amounts more compactly.

Standard Roman numerals are typically written from 1 to 3999; numbers beyond that range require alternative conventions such as overlines to indicate larger magnitudes. MMMCMXLVI thus fits within the conventional modern usage of Roman numerals. The form can appear in historical inscriptions, numerals in puzzles, or as a stylistic date in fiction or media. The numeral is read as “three thousand nine hundred forty-six” in English.
