How MMMCCCXCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |

MMMCCCXCIX is written one place at a time, from the largest to the smallest: MMM (3000) + CCC (300) + XC (90) + IX (9) = 3399.
XC and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMMCCCIC
Why isn't 3399 written as MMMCCCIC?
I can only be subtracted from V and X, so IC (100 − 1) is not a valid pair. Write each place separately: MMM (3000) + CCC (300) + XC (90) + IX (9) = MMMCCCXCIX.
Wrong: MMMCCCLXXXXIX
Why isn't 3399 written as MMMCCCLXXXXIX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 3399 is MMMCCCXCIX.
Wrong: MMMCCCXCVIIII
Why isn't 3399 written as MMMCCCXCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3399 is MMMCCCXCIX.
