    Keyboard works too — type digits and operators, Enter to evaluate, Backspace to delete, Escape to clear.

    How it is calculated

    Standard operator precedence: brackets, then powers, then × and ÷, then + and −.

    Trigonometric functions accept degrees or radians — switch modes with the DEG/RAD key.

    Worked example

    Typing sin(30) in DEG mode gives 0.5. Typing 2^10 gives 1024. Typing √(144) + log(100) gives 14.
