CM and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMMDCCCCXCII
Why isn't 3992 written as MMMDCCCCXCII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 3992 is MMMCMXCII.
Wrong: MMMCMLXXXXII
Why isn't 3992 written as MMMCMLXXXXII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 3992 is MMMCMXCII.
Wrong: MMMDCCCCLXXXXII
Why isn't 3992 written as MMMDCCCCLXXXXII?
No symbol can be repeated four times in a row, so DCCCC and LXXXX are not used: 900 = CM, 90 = XC. Together they make MMMCMXCII.
