How MMMCMI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 900 | C (subtracted)M |
| Units | 1 | I |
| Total | 3901 | MMMCMI |
MMMCMI is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + I (1) = 3901.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMMDCCCCI
Why isn't 3901 written as MMMDCCCCI?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3901 is MMMCMI.
