| Read | Worth | Running total |
|---|---|---|
| CM | 900 | 900 |
| LXX | 70 | 970 |
| V | 5 | 975 |
The one place that scan can trip you up is the pair CM. 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 CM as one group and the rest of CMLXXV falls into place.
