How MMCDV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 400 | C (subtracted)D |
| Units | 5 | V |
| Total | 2405 | MMCDV |
MMCDV is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + V (5) = 2405.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMCCCCV
Why isn't 2405 written as MMCCCCV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2405 is MMCDV.
