How to read DCIV

| Read | Worth | Running total |
|---|---|---|
| DC | 600 | 600 |
| IV | 4 | 604 |
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 DCIV falls into place.
