About Calculator
The Calculator offers both a basic and a scientific mode. Basic mode handles everyday arithmetic — addition, subtraction, multiplication, and division — while scientific mode adds trigonometric functions, logarithms, exponents, roots, and memory operations.
It supports full keyboard input, so you can type calculations directly. Everything runs in the browser with no setup, and your calculations are not stored or sent anywhere.
