Question 1

Does this calculator support parentheses and operator precedence?

Accepted Answer

Yes — you can use parentheses to group calculations, and the calculator correctly applies standard order of operations (multiplication and division before addition and subtraction, powers evaluated right-to-left).

Question 2

What's the difference between DEG and RAD mode?

Accepted Answer

DEG mode treats angle inputs and outputs in degrees (0–360), while RAD mode uses radians (0–2π). Switch modes before using sin, cos, tan or their inverse functions depending on what your problem requires.

Question 3

Does the calculator save my calculation history?

Accepted Answer

The display shows your most recent expression above the result, but history isn't saved between sessions — everything runs locally in your browser and nothing is stored on our servers.
