MMMCM is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) = 3900.

CM is the only subtraction: the C before the M takes away 100, so CM = 900.

Common mistakes

Wrong: MMMDCCCC

Why isn't 3900 written as MMMDCCCC?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3900 is MMMCM.
