In Roman numerals, XX represents 20 and C represents 100. According to the rules of Roman numerals, a smaller value numeral can only be placed before a larger value numeral to subtract from it. Since XX (20) is smaller than C (100), it cannot be written in the reverse order as XXC (80) because it would violate the subtractive principle of Roman numerals.
