How DCLXXX is formed

|---|---|---|
| Hundreds | 600 | DC |
| Tens | 80 | LXXX |

DCLXXX is written one place at a time, from the largest to the smallest: DC (600) + LXXX (80) = 680.
Common mistakes
Wrong: DCXXC
Why isn't 680 written as DCXXC?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 680 is DCLXXX.
