Common mistakes
Wrong: MMMDCCCCXXXIX
Why isn't 3939 written as MMMDCCCCXXXIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3939 is MMMCMXXXIX.
Wrong: MMMCMXXXVIIII
Why isn't 3939 written as MMMCMXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3939 is MMMCMXXXIX.
Wrong: MMMDCCCCXXXVIIII
Why isn't 3939 written as MMMDCCCCXXXVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make MMMCMXXXIX.
