How MMMCMXV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 10 | X |
| Units | 5 | V |
| Total | 3915 | MMMCMXV |
MMMCMXV is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + X (10) + V (5) = 3915.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMMDCCCCXV
Why isn't 3915 written as MMMDCCCCXV?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3915 is MMMCMXV.
