The most useful reports include the exact equation, what you expected, what the calculator returned, and the page or language where you saw the issue.
What to report
Please send reproducible solver errors, unclear steps, graph mismatches, OCR transcription issues, broken LaTeX input, accessibility problems, or localization wording that sounds unnatural in context.
Corrections
When a mathematical bug is reproducible, the goal is to fix the logic and add a regression test for the reported equation so the same mistake is less likely to return.
