How to read CLXIX
Roman numerals are read left to right, largest value first, adding as you go. Scanning CLXIX one group at a time gives a running total that lands on 169:
| Read | Worth | Running total |
|---|---|---|
| C | 100 | 100 |
| LX | 60 | 160 |
| IX | 9 | 169 |
The one place that scan can trip you up is the pair IX. 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 IX as one group and the rest of CLXIX falls into place.
