How to read CMLXI
Roman numerals are read left to right, largest value first, adding as you go. Scanning CMLXI one group at a time gives a running total that lands on 961:
| Read | Worth | Running total |
|---|---|---|
| CM | 900 | 900 |
| LX | 60 | 960 |
| I | 1 | 961 |
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 CMLXI falls into place.
