How to read XLIX

| Read | Worth | Running total |
|---|---|---|
| XL | 40 | 40 |
| IX | 9 | 49 |
The one place that scan can trip you up is the pairs XL and IX. 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 XLIX falls into place.
