| Place | Value | Symbols |
|---|---|---|

MMCMIX is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + IX (9) = 2909.
CM and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMDCCCCIX
Why isn't 2909 written as MMDCCCCIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2909 is MMCMIX.
Wrong: MMCMVIIII
Why isn't 2909 written as MMCMVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2909 is MMCMIX.
Wrong: MMDCCCCVIIII
Why isn't 2909 written as MMDCCCCVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make MMCMIX.
