How CCCXCVIII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 300 | CCC |
| Tens | 90 | X (subtracted)C |
| Units | 8 | VIII |
| Total | 398 | CCCXCVIII |
CCCXCVIII is written one place at a time, from the largest to the smallest: CCC (300) + XC (90) + VIII (8) = 398.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: CCCLXXXXVIII
Why isn't 398 written as CCCLXXXXVIII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 398 is CCCXCVIII.
Wrong: CCCXCIIX
Why isn't 398 written as CCCXCIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 398 is CCCXCVIII.
