Reporting a calculation issue

Include the page URL, the numbers you entered, the answer you got and the answer you expected — calculation reports get checked against the formula and fixed within a day. If your school uses a different letter scale (7-point, no plus/minus, A at 94), tell us which institution and we'll consider adding it as an option.

Everything else

Suggestions for new calculators, accessibility problems, and advertising questions all go to the same address. We read everything; short messages get answered fastest.

What we can't help with

We can't dispute a grade with your school, interpret a specific professor's rounding policy, or provide official transcripts — those conversations belong with your instructor or registrar. What we can do is make sure the math on every page here is exactly right, so bring us anything that looks off.
