How CCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 200 | CC |
| Units | 9 | I (subtracted)X |
| Total | 209 | CCIX |
CCIX is written one place at a time, from the largest to the smallest: CC (200) + IX (9) = 209.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: CCVIIII
Why isn't 209 written as CCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 209 is CCIX.
