How CCCXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 300 | CCC |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 349 | CCCXLIX |
CCCXLIX is written one place at a time, from the largest to the smallest: CCC (300) + XL (40) + IX (9) = 349.
XL and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: CCCIL
Why isn't 349 written as CCCIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: CCC (300) + XL (40) + IX (9) = CCCXLIX.
Wrong: CCCXXXXIX
Why isn't 349 written as CCCXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 349 is CCCXLIX.
Wrong: CCCXLVIIII
Why isn't 349 written as CCCXLVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 349 is CCCXLIX.
