How to read CCCXIX
Roman numerals are read left to right, largest value first, adding as you go. Scanning CCCXIX one group at a time gives a running total that lands on 319:
| Read | Worth | Running total |
|---|---|---|
| CCC | 300 | 300 |
| X | 10 | 310 |
| IX | 9 | 319 |
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 CCCXIX falls into place.
