|---|---|---|
| Hundreds | 800 | DCCC |
| Tens | 10 | X |

DCCCX is written one place at a time, from the largest to the smallest: DCCC (800) + X (10) = 810.
Common mistakes
Wrong: CCMX
Why isn't 810 written as CCMX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 810 is DCCCX.
