How MMMCDXXXVIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 30 | XXX |
| Units | 8 | VIII |
| Total | 3438 | MMMCDXXXVIII |
MMMCDXXXVIII is written one place at a time, from the largest to the smallest: MMM (3000) + CD (400) + XXX (30) + VIII (8) = 3438.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMMCCCCXXXVIII
Why isn't 3438 written as MMMCCCCXXXVIII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3438 is MMMCDXXXVIII.
Wrong: MMMCDXXXIIX
Why isn't 3438 written as MMMCDXXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 3438 is MMMCDXXXVIII.
