| Read | Worth | Running total |
|---|---|---|
| DC | 600 | 600 |
| L | 50 | 650 |
| IV | 4 | 654 |
The one place that scan can trip you up is the pair IV. 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 IV as one group and the rest of DCLIV falls into place.
