How DCCCLXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 800 | DCCC |
| Tens | 70 | LXX |
| Units | 9 | I (subtracted)X |
| Total | 879 | DCCCLXXIX |
DCCCLXXIX is written one place at a time, from the largest to the smallest: DCCC (800) + LXX (70) + IX (9) = 879.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: DCCCLXXVIIII
Why isn't 879 written as DCCCLXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 879 is DCCCLXXIX.
Wrong: CCMLXXIX
Why isn't 879 written as CCMLXXIX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 879 is DCCCLXXIX.
