MMMCMXVIII is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + X (10) + VIII (8) = 3918.

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

Common mistakes

Wrong: MMMDCCCCXVIII

Why isn't 3918 written as MMMDCCCCXVIII?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3918 is MMMCMXVIII.

Wrong: MMMCMXIIX

Why isn't 3918 written as MMMCMXIIX?

Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 3918 is MMMCMXVIII.
