How DCCXCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 700 | DCC |
| Tens | 90 | X (subtracted)C |
| Units | 9 | I (subtracted)X |
| Total | 799 | DCCXCIX |
DCCXCIX is written one place at a time, from the largest to the smallest: DCC (700) + XC (90) + IX (9) = 799.
XC and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCIC
Why isn't 799 written as DCCIC?
I can only be subtracted from V and X, so IC (100 − 1) is not a valid pair. Write each place separately: DCC (700) + XC (90) + IX (9) = DCCXCIX.
Wrong: DCCLXXXXIX
Why isn't 799 written as DCCLXXXXIX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 799 is DCCXCIX.
Wrong: DCCXCVIIII
Why isn't 799 written as DCCXCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 799 is DCCXCIX.
