What to include in a correction report
- The calculator page URL.
- The input values, units and selected options.
- The result displayed and the result you expected.
- The browser or device, if the problem concerns the interface.
- A reference or an arithmetic check, when available.
For example: “On the percentage calculator, I selected percentage change, entered original 80 and new 100, and expected 25%.” This makes the report easy to reproduce.
