How MMMCDXC is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 90 | X (subtracted)C |
| Total | 3490 | MMMCDXC |
MMMCDXC is written one place at a time, from the largest to the smallest: MMM (3000) + CD (400) + XC (90) = 3490.
CD and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMMXD
Why isn't 3490 written as MMMXD?
X can only be subtracted from L and C, so XD (500 − 10) is not a valid pair. Write each place separately: MMM (3000) + CD (400) + XC (90) = MMMCDXC.
Wrong: MMMCCCCXC
Why isn't 3490 written as MMMCCCCXC?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3490 is MMMCDXC.
Wrong: MMMCDLXXXX
Why isn't 3490 written as MMMCDLXXXX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 3490 is MMMCDXC.
