How CMXXX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Tens | 30 | XXX |
| Total | 930 | CMXXX |
CMXXX is written one place at a time, from the largest to the smallest: CM (900) + XXX (30) = 930.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: DCCCCXXX
Why isn't 930 written as DCCCCXXX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 930 is CMXXX.
