How MMMDCCCXXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 30 | XXX |
| Units | 9 | I (subtracted)X |
| Total | 3839 | MMMDCCCXXXIX |
MMMDCCCXXXIX is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + XXX (30) + IX (9) = 3839.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMMDCCCXXXVIIII
Why isn't 3839 written as MMMDCCCXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3839 is MMMDCCCXXXIX.
Wrong: MMMCCMXXXIX
Why isn't 3839 written as MMMCCMXXXIX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3839 is MMMDCCCXXXIX.
