How MCDI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Units | 1 | I |
| Total | 1401 | MCDI |
MCDI is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + I (1) = 1401.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MCCCCI
Why isn't 1401 written as MCCCCI?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1401 is MCDI.
