How CDVI is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Units | 6 | VI |
| Total | 406 | CDVI |
CDVI is written one place at a time, from the largest to the smallest: CD (400) + VI (6) = 406.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCVI
Why isn't 406 written as CCCCVI?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 406 is CDVI.
