How CMLXXXV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |
| Units | 5 | V |
| Total | 985 | CMLXXXV |
CMLXXXV is written one place at a time, from the largest to the smallest: CM (900) + LXXX (80) + V (5) = 985.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: DCCCCLXXXV
Why isn't 985 written as DCCCCLXXXV?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 985 is CMLXXXV.
Wrong: CMXXCV
Why isn't 985 written as CMXXCV?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 985 is CMLXXXV.
