How MMMCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 100 | C |
| Units | 9 | I (subtracted)X |
| Total | 3109 | MMMCIX |
MMMCIX is written one place at a time, from the largest to the smallest: MMM (3000) + C (100) + IX (9) = 3109.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMMCVIIII
Why isn't 3109 written as MMMCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3109 is MMMCIX.
