MMMCMXXIV is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + XX (20) + IV (4) = 3924.
CM and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMMDCCCCXXIV
Why isn't 3924 written as MMMDCCCCXXIV?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3924 is MMMCMXXIV.
Wrong: MMMCMXXIIII
Why isn't 3924 written as MMMCMXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 3924 is MMMCMXXIV.
Wrong: MMMDCCCCXXIIII
Why isn't 3924 written as MMMDCCCCXXIIII?
No symbol can be repeated four times in a row, so DCCCC and IIII are not used: 900 = CM, 4 = IV. Together they make MMMCMXXIV.
