How CMIV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Units | 4 | I (subtracted)V |
| Total | 904 | CMIV |
CMIV is written one place at a time, from the largest to the smallest: CM (900) + IV (4) = 904.
CM and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCCCIV
Why isn't 904 written as DCCCCIV?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 904 is CMIV.
Wrong: CMIIII
Why isn't 904 written as CMIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 904 is CMIV.
Wrong: DCCCCIIII
Why isn't 904 written as DCCCCIIII?
No symbol can be repeated four times in a row, so DCCCC and IIII are not used: 900 = CM, 4 = IV. Together they make CMIV.
