MMDXI

MMDXI is a sequence of Roman numerals. In the Roman numeral system, M represents 1000, D represents 500, X represents 10, and I represents 1. When combining these numerals, the values are typically added together. Therefore, MMXI can be interpreted as 1000 + 1000 + 10 + 1. This results in the number 2011. The sequence MMXI is a straightforward representation of the Gregorian year 2011. It follows the standard additive principle of Roman numerals, where symbols are placed from left to right in order of value, starting with the largest. There are no instances of subtractive notation, such as IV for 4 or IX for 9, within MMXI. The numeral is a clear and unambiguous representation of the number 2011.
