Report a calculation problem
A useful calculation report includes:
- The tool's page URL and the calculation mode.
- A short sample that reproduces the problem.
- The result you expected, the result displayed and your calculation rule or source.
- The browser and device type if the form or controls failed.
Use invented or non-sensitive values whenever possible. A date issue can usually be demonstrated without a real birthday. Never send passwords, session cookies, identity documents, private grade reports or account recovery links.
Content, privacy and advertising questions
For a content correction, identify the paragraph or formula and explain the change. For privacy questions, state the category of data or browser storage you are asking about rather than sending private records. Include the affected page if an advertisement interferes with a control.
