MMMCMXCIII is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + XC (90) + III (3) = 3993.

Common mistakes

Wrong: MMMDCCCCXCIII

Why isn't 3993 written as MMMDCCCCXCIII?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3993 is MMMCMXCIII.

Wrong: MMMCMLXXXXIII

Why isn't 3993 written as MMMCMLXXXXIII?

A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 3993 is MMMCMXCIII.

Wrong: MMMDCCCCLXXXXIII

Why isn't 3993 written as MMMDCCCCLXXXXIII?

No symbol can be repeated four times in a row, so DCCCC and LXXXX are not used: 900 = CM, 90 = XC. Together they make MMMCMXCIII.
