How to read CLIV
Roman numerals are read left to right, largest value first, adding as you go. Scanning CLIV one group at a time gives a running total that lands on 154:
| Read | Worth | Running total |
|---|---|---|
| C | 100 | 100 |
| L | 50 | 150 |
| IV | 4 | 154 |
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 CLIV falls into place.
