How DCCCI is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 800 | DCCC |
| Units | 1 | I |
| Total | 801 | DCCCI |
DCCCI is written one place at a time, from the largest to the smallest: DCCC (800) + I (1) = 801.
Common mistakes
Wrong: CCMI
Why isn't 801 written as CCMI?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 801 is DCCCI.
