How MMMCMLI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 50 | L |
| Units | 1 | I |
| Total | 3951 | MMMCMLI |
MMMCMLI is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + L (50) + I (1) = 3951.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMMDCCCCLI
Why isn't 3951 written as MMMDCCCCLI?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3951 is MMMCMLI.
