Frequently asked questions
Is this scientific calculator free to use?
Yes. Every mode — scientific, fraction, matrix, vector and complex — is free, needs no sign-up and runs entirely in your browser.
Can I use my keyboard?
Yes. Type digits and operators directly, press Enter or = to evaluate, Backspace to delete and Escape to clear everything.
Does it work in degrees and radians?
Tap the DEG key on the device to cycle between degrees, radians and gradians. The active unit is shown on the display.
Is my calculation history stored anywhere?
No. History lives only in the current browser tab and is cleared when you close it or press Clear history.
