How MMMDCCCLXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 60 | LX |
| Units | 9 | I (subtracted)X |
| Total | 3869 | MMMDCCCLXIX |
MMMDCCCLXIX is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + LX (60) + IX (9) = 3869.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMMDCCCLXVIIII
Why isn't 3869 written as MMMDCCCLXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3869 is MMMDCCCLXIX.
Wrong: MMMCCMLXIX
Why isn't 3869 written as MMMCCMLXIX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3869 is MMMDCCCLXIX.
