How to read LXXXIV
Roman numerals are read left to right, largest value first, adding as you go. Scanning LXXXIV one group at a time gives a running total that lands on 84:
| Read | Worth | Running total |
|---|---|---|
| LXXX | 80 | 80 |
| IV | 4 | 84 |
The one place that scan can trip you up is the pair IV. 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 IV as one group and the rest of LXXXIV falls into place.
