How MDCCCXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 800 | DCCC |
| Tens | 20 | XX |
| Units | 9 | I (subtracted)X |
| Total | 1829 | MDCCCXXIX |
MDCCCXXIX is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + XX (20) + IX (9) = 1829.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MDCCCXXVIIII
Why isn't 1829 written as MDCCCXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1829 is MDCCCXXIX.
Wrong: MCCMXXIX
Why isn't 1829 written as MCCMXXIX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1829 is MDCCCXXIX.
