MMCCCXXI

MMCCCXXI is the Roman numeral representation of the number 2321. The system of Roman numerals uses letters to represent numerical values. The numeral M represents 1000, C represents 100, X represents 10, and I represents 1. When the numerals are arranged in descending order, their values are added together. Therefore, in MMCCCXXI, we have M (1000) + M (1000) + C (100) + C (100) + C (100) + X (10) + X (10) + I (1). This summation results in 1000 + 1000 + 100 + 100 + 100 + 10 + 10 + 1, which equals 2321. There are no instances of subtractive notation in MMCCCXXI, such as placing a smaller numeral before a larger one (e.g., IV for 4). The number 2321 is an integer.
