How CDLXXX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 80 | LXXX |
| Total | 480 | CDLXXX |
CDLXXX is written one place at a time, from the largest to the smallest: CD (400) + LXXX (80) = 480.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: CCCCLXXX
Why isn't 480 written as CCCCLXXX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 480 is CDLXXX.
Wrong: CDXXC
Why isn't 480 written as CDXXC?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 480 is CDLXXX.
