How DCXCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 600 | DC |
| Tens | 90 | X (subtracted)C |
| Units | 9 | I (subtracted)X |
| Total | 699 | DCXCIX |
DCXCIX is written one place at a time, from the largest to the smallest: DC (600) + XC (90) + IX (9) = 699.
XC and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCIC
Why isn't 699 written as DCIC?
I can only be subtracted from V and X, so IC (100 − 1) is not a valid pair. Write each place separately: DC (600) + XC (90) + IX (9) = DCXCIX.
Wrong: DCLXXXXIX
Why isn't 699 written as DCLXXXXIX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 699 is DCXCIX.
Wrong: DCXCVIIII
Why isn't 699 written as DCXCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 699 is DCXCIX.
