Common mistakes
Wrong: MMCCCCXCVII
Why isn't 2497 written as MMCCCCXCVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2497 is MMCDXCVII.
Wrong: MMCDLXXXXVII
Why isn't 2497 written as MMCDLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 2497 is MMCDXCVII.
Wrong: MMCCCCLXXXXVII
Why isn't 2497 written as MMCCCCLXXXXVII?
No symbol can be repeated four times in a row, so CCCC and LXXXX are not used: 400 = CD, 90 = XC. Together they make MMCDXCVII.
