How DCXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 600 | DC |
| Tens | 20 | XX |
| Units | 9 | I (subtracted)X |
| Total | 629 | DCXXIX |
DCXXIX is written one place at a time, from the largest to the smallest: DC (600) + XX (20) + IX (9) = 629.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: DCXXVIIII
Why isn't 629 written as DCXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 629 is DCXXIX.
