How MCDV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Units | 5 | V |
| Total | 1405 | MCDV |
MCDV is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + V (5) = 1405.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MCCCCV
Why isn't 1405 written as MCCCCV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1405 is MCDV.
