How CDXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 10 | X |
| Units | 9 | I (subtracted)X |
| Total | 419 | CDXIX |
CDXIX is written one place at a time, from the largest to the smallest: CD (400) + X (10) + IX (9) = 419.
CD and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: CCCCXIX
Why isn't 419 written as CCCCXIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 419 is CDXIX.
Wrong: CDXVIIII
Why isn't 419 written as CDXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 419 is CDXIX.
Wrong: CCCCXVIIII
Why isn't 419 written as CCCCXVIIII?
No symbol can be repeated four times in a row, so CCCC and VIIII are not used: 400 = CD, 9 = IX. Together they make CDXIX.
