How CXCVII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 100 | C |
| Tens | 90 | X (subtracted)C |
| Units | 7 | VII |
| Total | 197 | CXCVII |
CXCVII is written one place at a time, from the largest to the smallest: C (100) + XC (90) + VII (7) = 197.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: CLXXXXVII
Why isn't 197 written as CLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 197 is CXCVII.
