How CXCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 100 | C |
| Tens | 90 | X (subtracted)C |
| Units | 9 | I (subtracted)X |
| Total | 199 | CXCIX |
CXCIX is written one place at a time, from the largest to the smallest: C (100) + XC (90) + IX (9) = 199.
XC and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: CIC
Why isn't 199 written as CIC?
I can only be subtracted from V and X, so IC (100 − 1) is not a valid pair. Write each place separately: C (100) + XC (90) + IX (9) = CXCIX.
Wrong: CLXXXXIX
Why isn't 199 written as CLXXXXIX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 199 is CXCIX.
Wrong: CXCVIIII
Why isn't 199 written as CXCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 199 is CXCIX.
