Common mistakes
Wrong: MMDCCCCLXXIX
Why isn't 2979 written as MMDCCCCLXXIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2979 is MMCMLXXIX.
Wrong: MMCMLXXVIIII
Why isn't 2979 written as MMCMLXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2979 is MMCMLXXIX.
Wrong: MMDCCCCLXXVIIII
Why isn't 2979 written as MMDCCCCLXXVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make MMCMLXXIX.
