How CDXXII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 20 | XX |
| Units | 2 | II |
| Total | 422 | CDXXII |
CDXXII is written one place at a time, from the largest to the smallest: CD (400) + XX (20) + II (2) = 422.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCXXII
Why isn't 422 written as CCCCXXII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 422 is CDXXII.
