| Place | Value | Symbols |
|---|---|---|

MMMCMXL is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + XL (40) = 3940.
CM and XL are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMMDCCCCXL
Why isn't 3940 written as MMMDCCCCXL?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3940 is MMMCMXL.
Wrong: MMMCMXXXX
Why isn't 3940 written as MMMCMXXXX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3940 is MMMCMXL.
Wrong: MMMDCCCCXXXX
Why isn't 3940 written as MMMDCCCCXXXX?
No symbol can be repeated four times in a row, so DCCCC and XXXX are not used: 900 = CM, 40 = XL. Together they make MMMCMXL.
