How MMDCCCXXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 800 | DCCC |
| Tens | 30 | XXX |
| Units | 9 | I (subtracted)X |
| Total | 2839 | MMDCCCXXXIX |
MMDCCCXXXIX is written one place at a time, from the largest to the smallest: MM (2000) + DCCC (800) + XXX (30) + IX (9) = 2839.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMDCCCXXXVIIII
Why isn't 2839 written as MMDCCCXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2839 is MMDCCCXXXIX.
Wrong: MMCCMXXXIX
Why isn't 2839 written as MMCCMXXXIX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 2839 is MMDCCCXXXIX.
