How CDLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 50 | L |
| Units | 9 | I (subtracted)X |
| Total | 459 | CDLIX |
CDLIX is written one place at a time, from the largest to the smallest: CD (400) + L (50) + IX (9) = 459.
CD and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: CCCCLIX
Why isn't 459 written as CCCCLIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 459 is CDLIX.
Wrong: CDLVIIII
Why isn't 459 written as CDLVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 459 is CDLIX.
Wrong: CCCCLVIIII
Why isn't 459 written as CCCCLVIIII?
No symbol can be repeated four times in a row, so CCCC and VIIII are not used: 400 = CD, 9 = IX. Together they make CDLIX.
