How MMDIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 500 | D |
| Units | 9 | I (subtracted)X |
| Total | 2509 | MMDIX |
MMDIX is written one place at a time, from the largest to the smallest: MM (2000) + D (500) + IX (9) = 2509.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMDVIIII
Why isn't 2509 written as MMDVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2509 is MMDIX.
