How MMCMXI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 10 | X |
| Units | 1 | I |
| Total | 2911 | MMCMXI |
MMCMXI is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + X (10) + I (1) = 2911.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMDCCCCXI
Why isn't 2911 written as MMDCCCCXI?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2911 is MMCMXI.
