How MMDCCXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 700 | DCC |
| Tens | 20 | XX |
| Units | 9 | I (subtracted)X |
| Total | 2729 | MMDCCXXIX |
MMDCCXXIX is written one place at a time, from the largest to the smallest: MM (2000) + DCC (700) + XX (20) + IX (9) = 2729.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMDCCXXVIIII
Why isn't 2729 written as MMDCCXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2729 is MMDCCXXIX.
