Common mistakes
Wrong: MMMDCCCCLXXIX
Why isn't 3979 written as MMMDCCCCLXXIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3979 is MMMCMLXXIX.
Wrong: MMMCMLXXVIIII
Why isn't 3979 written as MMMCMLXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3979 is MMMCMLXXIX.
Wrong: MMMDCCCCLXXVIIII
Why isn't 3979 written as MMMDCCCCLXXVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make MMMCMLXXIX.
