How CMIII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Units | 3 | III |
| Total | 903 | CMIII |
CMIII is written one place at a time, from the largest to the smallest: CM (900) + III (3) = 903.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: DCCCCIII
Why isn't 903 written as DCCCCIII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 903 is CMIII.
