Common mistakes

Wrong: MMMDCCCCLXXXIV

Why isn't 3984 written as MMMDCCCCLXXXIV?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3984 is MMMCMLXXXIV.

Wrong: MMMCMLXXXIIII

Why isn't 3984 written as MMMCMLXXXIIII?

A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 3984 is MMMCMLXXXIV.

Wrong: MMMDCCCCLXXXIIII

Why isn't 3984 written as MMMDCCCCLXXXIIII?

No symbol can be repeated four times in a row, so DCCCC and IIII are not used: 900 = CM, 4 = IV. Together they make MMMCMLXXXIV.
