How CMLXXX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |
| Total | 980 | CMLXXX |
CMLXXX is written one place at a time, from the largest to the smallest: CM (900) + LXXX (80) = 980.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: DCCCCLXXX
Why isn't 980 written as DCCCCLXXX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 980 is CMLXXX.
Wrong: CMXXC
Why isn't 980 written as CMXXC?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 980 is CMLXXX.
