How CDXXXVII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 30 | XXX |
| Units | 7 | VII |
| Total | 437 | CDXXXVII |
CDXXXVII is written one place at a time, from the largest to the smallest: CD (400) + XXX (30) + VII (7) = 437.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCXXXVII
Why isn't 437 written as CCCCXXXVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 437 is CDXXXVII.
