How MMCXXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 100 | C |
| Tens | 30 | XXX |
| Units | 9 | I (subtracted)X |
| Total | 2139 | MMCXXXIX |
MMCXXXIX is written one place at a time, from the largest to the smallest: MM (2000) + C (100) + XXX (30) + IX (9) = 2139.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMCXXXVIIII
Why isn't 2139 written as MMCXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2139 is MMCXXXIX.
