| Read | Worth | Running total |
|---|---|---|
| DCCC | 800 | 800 |
| X | 10 | 810 |
| IX | 9 | 819 |
The one place that scan can trip you up is the pair 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 IX as one group and the rest of DCCCXIX falls into place.
