CM and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCCCXIX
Why isn't 919 written as DCCCCXIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 919 is CMXIX.
Wrong: CMXVIIII
Why isn't 919 written as CMXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 919 is CMXIX.
Wrong: DCCCCXVIIII
Why isn't 919 written as DCCCCXVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make CMXIX.
