How to read XLVIII

| Read | Worth | Running total |
|---|---|---|
| XL | 40 | 40 |
| VIII | 8 | 48 |
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 XLVIII falls into place.
