How CDVII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Units | 7 | VII |
| Total | 407 | CDVII |
CDVII is written one place at a time, from the largest to the smallest: CD (400) + VII (7) = 407.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCVII
Why isn't 407 written as CCCCVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 407 is CDVII.
