Scientific Calculator not working? Here's how to fix it
Most issues with the Scientific Calculator are small and fixable in seconds. Work through these in order.
1. Trig results look wrong
Check your angle mode. If you're solving in degrees but the mode is set to radians — or vice versa — sine, cosine, and tangent will return unexpected values. Select the mode that matches your input units.
2. The result is wrong or nothing evaluates
Review your expression for syntax errors or missing operators. Make sure every opening bracket has a closing one and that you didn't place two operators together (like `3 ** 5` or `2 ++ 3`).
3. A result doesn't update as expected
The calculator evaluates as you type. If the display seems stale, clear the input and re-enter the expression. Partial or incomplete expressions may not produce a final result.
4. Very large or small answers overflow
For extreme values, results may show in scientific notation. This is normal — a huge exponent doesn't mean the answer is wrong, just that it's too large for standard formatting.
5. The tool won't load at all
Reload the page or open it in a fresh tab. If an extension blocks scripts, try private (incognito) mode — the calculator needs JavaScript, which is on by default in every modern browser.
Still stuck?
Try a different current browser (Chrome, Firefox, Safari, Edge). The tool behaves the same everywhere, so a fresh environment usually resolves the last edge cases.
Verdict
Most problems with Scientific Calculator are solved by checking the angle mode, fixing brackets or syntax, and reloading the page.
