How CDLV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 50 | L |
| Units | 5 | V |
| Total | 455 | CDLV |
CDLV is written one place at a time, from the largest to the smallest: CD (400) + L (50) + V (5) = 455.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCLV
Why isn't 455 written as CCCCLV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 455 is CDLV.
