What the calculator can do
- Basic arithmetic — add, subtract, multiply, and divide, with parentheses for grouping.
- Powers and roots — square (x²), any power (xʸ), and square root (√).
- Trigonometry — sin, cos, and tan (in radians).
- Logarithms — natural log (ln) and base-10 log (log).
- Constants — π (pi) and e, plus the modulo (%) operator for remainders.
It evaluates the whole expression at once following standard order of operations, so you can chain several steps before pressing =.
Frequently asked questions
Do the trig functions use degrees or radians?
Radians. To work in degrees, convert first — for example, the sine of 30° is
sin(30 * pi / 180).How do I raise a number to a power?
Use the xʸ key (the
^ operator) — for example 2 ^ 10 gives 1024. The x² key squares the current value.What do AC and ⌫ do?
AC clears the entire expression and result. ⌫ (backspace) removes just the last character, so you can fix a typo without starting over.
