CM and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCCCXXIV
Why isn't 924 written as DCCCCXXIV?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 924 is CMXXIV.
Wrong: CMXXIIII
Why isn't 924 written as CMXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 924 is CMXXIV.
Wrong: DCCCCXXIIII
Why isn't 924 written as DCCCCXXIIII?
No symbol can be repeated four times in a row, so DCCCC and IIII are not used: 900 = CM, 4 = IV. Together they make CMXXIV.
