Common mistakes
Wrong: MMMDCCCCXXIX
Why isn't 3929 written as MMMDCCCCXXIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3929 is MMMCMXXIX.
Wrong: MMMCMXXVIIII
Why isn't 3929 written as MMMCMXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3929 is MMMCMXXIX.
Wrong: MMMDCCCCXXVIIII
Why isn't 3929 written as MMMDCCCCXXVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make MMMCMXXIX.
