How to read CCLIX
Roman numerals are read left to right, largest value first, adding as you go. Scanning CCLIX one group at a time gives a running total that lands on 259:
| Read | Worth | Running total |
|---|---|---|
| CC | 200 | 200 |
| L | 50 | 250 |
| IX | 9 | 259 |
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 CCLIX falls into place.
