CMLXXXIV is written one place at a time, from the largest to the smallest: CM (900) + LXXX (80) + IV (4) = 984.
CM and IV are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCCCLXXXIV
Why isn't 984 written as DCCCCLXXXIV?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 984 is CMLXXXIV.
Wrong: CMLXXXIIII
Why isn't 984 written as CMLXXXIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 984 is CMLXXXIV.
Wrong: DCCCCLXXXIIII
Why isn't 984 written as DCCCCLXXXIIII?
No symbol can be repeated four times in a row, so DCCCC and IIII are not used: 900 = CM, 4 = IV. Together they make CMLXXXIV.
