How CCXCVII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 200 | CC |
| Tens | 90 | X (subtracted)C |
| Units | 7 | VII |
| Total | 297 | CCXCVII |
CCXCVII is written one place at a time, from the largest to the smallest: CC (200) + XC (90) + VII (7) = 297.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: CCLXXXXVII
Why isn't 297 written as CCLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 297 is CCXCVII.
