How MCXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 100 | C |
| Tens | 20 | XX |
| Units | 9 | I (subtracted)X |
| Total | 1129 | MCXXIX |
MCXXIX is written one place at a time, from the largest to the smallest: M (1000) + C (100) + XX (20) + IX (9) = 1129.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MCXXVIIII
Why isn't 1129 written as MCXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1129 is MCXXIX.
