How MMMCMXVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 10 | X |
| Units | 7 | VII |

MMMCMXVII is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + X (10) + VII (7) = 3917.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMMDCCCCXVII
Why isn't 3917 written as MMMDCCCCXVII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3917 is MMMCMXVII.
