How MCDIV is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Units | 4 | I (subtracted)V |
| Total | 1404 | MCDIV |
MCDIV is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + IV (4) = 1404.
CD and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MCCCCIV
Why isn't 1404 written as MCCCCIV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1404 is MCDIV.
Wrong: MCDIIII
Why isn't 1404 written as MCDIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 1404 is MCDIV.
Wrong: MCCCCIIII
Why isn't 1404 written as MCCCCIIII?
No symbol can be repeated four times in a row, so CCCC and IIII are not used: 400 = CD, 4 = IV. Together they make MCDIV.
