How CLXXX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 100 | C |
| Tens | 80 | LXXX |
| Total | 180 | CLXXX |
CLXXX is written one place at a time, from the largest to the smallest: C (100) + LXXX (80) = 180.
Common mistakes
Wrong: CXXC
Why isn't 180 written as CXXC?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 180 is CLXXX.
