How to read CXLVIII
Roman numerals are read left to right, largest value first, adding as you go. Scanning CXLVIII one group at a time gives a running total that lands on 148:
| Read | Worth | Running total |
|---|---|---|
| C | 100 | 100 |
| XL | 40 | 140 |
| VIII | 8 | 148 |
The one place that scan can trip you up is the pair XL. 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 XL as one group and the rest of CXLVIII falls into place.
