How DCCCLI is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 800 | DCCC |
| Tens | 50 | L |
| Units | 1 | I |
| Total | 851 | DCCCLI |
DCCCLI is written one place at a time, from the largest to the smallest: DCCC (800) + L (50) + I (1) = 851.
Common mistakes
Wrong: CCMLI
Why isn't 851 written as CCMLI?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 851 is DCCCLI.
