|---|---|---|

CMXXIX is written one place at a time, from the largest to the smallest: CM (900) + XX (20) + IX (9) = 929.
CM and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCCCXXIX
Why isn't 929 written as DCCCCXXIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 929 is CMXXIX.
Wrong: CMXXVIIII
Why isn't 929 written as CMXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 929 is CMXXIX.
Wrong: DCCCCXXVIIII
Why isn't 929 written as DCCCCXXVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make CMXXIX.
