Use this page to report a clear issue with a calculation, link, source note, wording, or page layout.
Use Corrections when you can point to a math result, source note, link, sentence, or layout problem. A report is easier to check when it includes a page URL, sample values, and the result you expected.

Include the page URL, the values you entered, the result you saw, and the result you expected.
Use example numbers. Do not send card numbers, full receipts, home addresses, or other private details.
