MMMCMLXXXVIII is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + LXXX (80) + VIII (8) = 3988.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMMDCCCCLXXXVIII
Why isn't 3988 written as MMMDCCCCLXXXVIII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3988 is MMMCMLXXXVIII.
Wrong: MMMCMXXCVIII
Why isn't 3988 written as MMMCMXXCVIII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 3988 is MMMCMLXXXVIII.
Wrong: MMMCMLXXXIIX
Why isn't 3988 written as MMMCMLXXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 3988 is MMMCMLXXXVIII.
