How CDLXXXV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 80 | LXXX |
| Units | 5 | V |
| Total | 485 | CDLXXXV |
CDLXXXV is written one place at a time, from the largest to the smallest: CD (400) + LXXX (80) + V (5) = 485.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCLXXXV
Why isn't 485 written as CCCCLXXXV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 485 is CDLXXXV.
Wrong: CDXXCV
Why isn't 485 written as CDXXCV?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 485 is CDLXXXV.
