| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |

CMLXXXIX is written one place at a time, from the largest to the smallest: CM (900) + LXXX (80) + IX (9) = 989.
CM and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCCCLXXXIX
Why isn't 989 written as DCCCCLXXXIX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 989 is CMLXXXIX.
Wrong: CMLXXXVIIII
Why isn't 989 written as CMLXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 989 is CMLXXXIX.
Wrong: DCCCCLXXXVIIII
Why isn't 989 written as DCCCCLXXXVIIII?
No symbol can be repeated four times in a row, so DCCCC and VIIII are not used: 900 = CM, 9 = IX. Together they make CMLXXXIX.
