How to read CCCXXXIV

| Read | Worth | Running total |
|---|---|---|
| CCC | 300 | 300 |
| XXX | 30 | 330 |
| IV | 4 | 334 |
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 CCCXXXIV falls into place.
