How MCDXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Tens | 20 | XX |
| Units | 9 | I (subtracted)X |

MCDXXIX is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + XX (20) + IX (9) = 1429.
CD and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MCCCCXXIX
Why isn't 1429 written as MCCCCXXIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1429 is MCDXXIX.
Wrong: MCDXXVIIII
Why isn't 1429 written as MCDXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1429 is MCDXXIX.
Wrong: MCCCCXXVIIII
Why isn't 1429 written as MCCCCXXVIIII?
No symbol can be repeated four times in a row, so CCCC and VIIII are not used: 400 = CD, 9 = IX. Together they make MCDXXIX.
