How MDCCCV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 800 | DCCC |
| Units | 5 | V |
| Total | 1805 | MDCCCV |
MDCCCV is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + V (5) = 1805.
Common mistakes
Wrong: MCCMV
Why isn't 1805 written as MCCMV?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1805 is MDCCCV.
