How CMI is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Units | 1 | I |
| Total | 901 | CMI |
CMI is written one place at a time, from the largest to the smallest: CM (900) + I (1) = 901.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: DCCCCI
Why isn't 901 written as DCCCCI?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 901 is CMI.
