Common mistakes
Wrong: CCCCXCVIII
Why isn't 498 written as CCCCXCVIII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 498 is CDXCVIII.
Wrong: CDLXXXXVIII
Why isn't 498 written as CDLXXXXVIII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 498 is CDXCVIII.
Wrong: CCCCLXXXXVIII
Why isn't 498 written as CCCCLXXXXVIII?
No symbol can be repeated four times in a row, so CCCC and LXXXX are not used: 400 = CD, 90 = XC. Together they make CDXCVIII.
