How DCCLXXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 700 | DCC |
| Tens | 80 | LXXX |
| Units | 9 | I (subtracted)X |
| Total | 789 | DCCLXXXIX |
DCCLXXXIX is written one place at a time, from the largest to the smallest: DCC (700) + LXXX (80) + IX (9) = 789.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: DCCLXXXVIIII
Why isn't 789 written as DCCLXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 789 is DCCLXXXIX.
Wrong: DCCXXCIX
Why isn't 789 written as DCCXXCIX?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 789 is DCCLXXXIX.
