How DCCXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 700 | DCC |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 749 | DCCXLIX |
DCCXLIX is written one place at a time, from the largest to the smallest: DCC (700) + XL (40) + IX (9) = 749.
XL and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCIL
Why isn't 749 written as DCCIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: DCC (700) + XL (40) + IX (9) = DCCXLIX.
Wrong: DCCXXXXIX
Why isn't 749 written as DCCXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 749 is DCCXLIX.
Wrong: DCCXLVIIII
Why isn't 749 written as DCCXLVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 749 is DCCXLIX.
