How to read CCCLXIV
Roman numerals are read left to right, largest value first, adding as you go. Scanning CCCLXIV one group at a time gives a running total that lands on 364:
| Read | Worth | Running total |
|---|---|---|
| CCC | 300 | 300 |
| LX | 60 | 360 |
| IV | 4 | 364 |
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 CCCLXIV falls into place.
