| Read | Worth | Running total |
|---|---|---|
| D | 500 | 500 |
| XL | 40 | 540 |
| VIII | 8 | 548 |
The one place that scan can trip you up is the pair XL. 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 XL as one group and the rest of DXLVIII falls into place.
