Common mistakes
Wrong: MMDCCCCXLVII
Why isn't 2947 written as MMDCCCCXLVII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2947 is MMCMXLVII.
Wrong: MMCMXXXXVII
Why isn't 2947 written as MMCMXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2947 is MMCMXLVII.
Wrong: MMDCCCCXXXXVII
Why isn't 2947 written as MMDCCCCXXXXVII?
No symbol can be repeated four times in a row, so DCCCC and XXXX are not used: 900 = CM, 40 = XL. Together they make MMCMXLVII.
