How CMXX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Tens | 20 | XX |
| Total | 920 | CMXX |
CMXX is written one place at a time, from the largest to the smallest: CM (900) + XX (20) = 920.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: DCCCCXX
Why isn't 920 written as DCCCCXX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 920 is CMXX.
