How MMCCCLXXXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 300 | CCC |
| Tens | 80 | LXXX |
| Units | 9 | I (subtracted)X |
| Total | 2389 | MMCCCLXXXIX |
MMCCCLXXXIX is written one place at a time, from the largest to the smallest: MM (2000) + CCC (300) + LXXX (80) + IX (9) = 2389.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMCCCLXXXVIIII
Why isn't 2389 written as MMCCCLXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2389 is MMCCCLXXXIX.
Wrong: MMCCCXXCIX
Why isn't 2389 written as MMCCCXXCIX?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2389 is MMCCCLXXXIX.
