How CDXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 449 | CDXLIX |
CDXLIX is written one place at a time, from the largest to the smallest: CD (400) + XL (40) + IX (9) = 449.
CD, XL, and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: CDIL
Why isn't 449 written as CDIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: CD (400) + XL (40) + IX (9) = CDXLIX.
Wrong: CCCCXLIX
Why isn't 449 written as CCCCXLIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 449 is CDXLIX.
Wrong: CDXXXXIX
Why isn't 449 written as CDXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 449 is CDXLIX.
