How MMMDCCCXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 20 | XX |
| Units | 9 | I (subtracted)X |
| Total | 3829 | MMMDCCCXXIX |
MMMDCCCXXIX is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + XX (20) + IX (9) = 3829.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMMDCCCXXVIIII
Why isn't 3829 written as MMMDCCCXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3829 is MMMDCCCXXIX.
Wrong: MMMCCMXXIX
Why isn't 3829 written as MMMCCMXXIX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3829 is MMMDCCCXXIX.
