|---|---|---|
| CM | 900 | 900 |

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 CMXII falls into place.
