How to Report a Calculation Error
Accuracy is our top priority, so error reports go straight to the front of the line. A helpful report answers four questions:
- Which calculator did you use? A link to the page is perfect.
- What exactly did you type into each box?
- What answer did the tool show?
- What answer did you expect, and where did that answer come from, such as a textbook or your teacher?
A screenshot helps too. Once we confirm the issue, we fix the tool, retest it and let you know.
