This online calculator handles the basic operations as well as percentages, powers and roots. In scientific mode you also get trigonometric functions (sine, cosine, tangent), logarithms, the number Pi and Euler's number – switchable between degrees and radians.

You can enter complete expressions with brackets, using the mouse, touch or your keyboard directly. The history remembers the last ten calculations so you can reuse results anytime. Everything runs locally in your browser.
