| Read | Worth | Running total |
|---|---|---|
| C | 100 | 100 |
| XC | 90 | 190 |
| VII | 7 | 197 |
The one place that scan can trip you up is the pair XC. A smaller letter sitting in front of a larger one is subtracted, not added, so you have to read those two letters as a single unit rather than one at a time. Treat XC as one group and the rest of CXCVII falls into place.
