How MDCCCX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 800 | DCCC |
| Tens | 10 | X |
| Total | 1810 | MDCCCX |
MDCCCX is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + X (10) = 1810.
Common mistakes
Wrong: MCCMX
Why isn't 1810 written as MCCMX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1810 is MDCCCX.
