XXIXCDLXXXV
XXIXCDLXXXV is a representation of a number. This particular notation is a combination of Roman numerals. To decipher it, we break it down into its constituent parts and their corresponding values. X represents 10, I represents 1, C represents 100, D represents 500, L represents 50, and V represents 5. The subtractive principle in Roman numerals is also applied here. When a smaller numeral precedes a larger one, it is subtracted from the larger one. For example, IX is 9 (10-1), XC is 90 (100-10), and CD is 400 (500-100).
Applying these rules to XXIXCDLXXXV, we can interpret it as follows: XX is 20. IX is 9.
