MMCMDCCCXXII

MMDCCCXXII is the Roman numeral representation of the number 2822. The system of Roman numerals uses letters to represent numerical values. In this case, M represents 1000, so MM signifies 2000. D represents 500, so adding it to 2000 gives 2500. C represents 100, so CCC means 300. X represents 10, so XX signifies 20. Finally, II represents 2. Therefore, combining these, MM (2000) + D (500) + CCC (300) + XX (20) + II (2) equals 2822. The system generally places larger values before smaller ones, with exceptions for subtractive notation (though not present in this specific number). Understanding Roman numerals involves recognizing the values of individual letters and their customary order of combination.
