How MMMCMXXXVIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 30 | XXX |
| Units | 8 | VIII |
| Total | 3938 | MMMCMXXXVIII |
MMMCMXXXVIII is written one place at a time, from the largest to the smallest: MMM (3000) + CM (900) + XXX (30) + VIII (8) = 3938.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMMDCCCCXXXVIII
Why isn't 3938 written as MMMDCCCCXXXVIII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3938 is MMMCMXXXVIII.
Wrong: MMMCMXXXIIX
Why isn't 3938 written as MMMCMXXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 3938 is MMMCMXXXVIII.
