How CDLVIII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 50 | L |
| Units | 8 | VIII |
| Total | 458 | CDLVIII |
CDLVIII is written one place at a time, from the largest to the smallest: CD (400) + L (50) + VIII (8) = 458.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCLVIII
Why isn't 458 written as CCCCLVIII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 458 is CDLVIII.
Wrong: CDLIIX
Why isn't 458 written as CDLIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 458 is CDLVIII.
