How MCCCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 300 | CCC |
| Units | 9 | I (subtracted)X |
| Total | 1309 | MCCCIX |
MCCCIX is written one place at a time, from the largest to the smallest: M (1000) + CCC (300) + IX (9) = 1309.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MCCCVIIII
Why isn't 1309 written as MCCCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1309 is MCCCIX.
