How MDCCXCIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 700 | DCC |
| Tens | 90 | X (subtracted)C |
| Units | 9 | I (subtracted)X |
| Total | 1799 | MDCCXCIX |
MDCCXCIX is written one place at a time, from the largest to the smallest: M (1000) + DCC (700) + XC (90) + IX (9) = 1799.
XC and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MDCCIC
Why isn't 1799 written as MDCCIC?
I can only be subtracted from V and X, so IC (100 − 1) is not a valid pair. Write each place separately: M (1000) + DCC (700) + XC (90) + IX (9) = MDCCXCIX.
Wrong: MDCCLXXXXIX
Why isn't 1799 written as MDCCLXXXXIX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1799 is MDCCXCIX.
Wrong: MDCCXCVIIII
Why isn't 1799 written as MDCCXCVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1799 is MDCCXCIX.
