Advanced calculator with expression mode, common scientific functions, history, and DEG/RAD toggle.
Keyboard supported. Enter to evaluate. Use sin, cos, tan, asin, acos, atan, log, ln, sqrt, abs, pow, fact, pi, e.
The Scientific Calculator evaluates complex mathematical expressions with support for trigonometric, logarithmic, and power functions. It includes memory storage, a DEG/RAD toggle, full keyboard input, and a scrollable history, making it a powerful tool for students, engineers, and anyone who needs more than basic arithmetic.
A scientific calculator processes mathematical expressions that go beyond simple addition and subtraction. It handles functions like sine, cosine, tangent, logarithms, square roots, absolute values, exponents, and factorials. Unlike a basic calculator that works one operation at a time, this tool accepts full expressions, such as sin(30)+sqrt(16)+log(100), and evaluates them in one step. It also supports angle mode switching between degrees and radians, memory registers, and reusable answer recall. This browser-based version is completely free, requires no installation or login, and works on any device.
Type or tap a mathematical expression into the input field using the on-screen buttons or your keyboard. Click the equals button or press Enter to evaluate. The result appears instantly along with an entry in the scrollable history panel, which you can click to reload any previous expression. Toggle between DEG and RAD modes for trigonometric functions. Use the memory buttons to store, recall, add to, or clear a value across calculations. Everything runs locally in your browser with no data transmitted, making it suitable for exam prep, engineering tasks, and everyday calculations.
