How to use it
Tap the buttons to build an expression, then press =. Use parentheses to control order of operations, and the DEG/RAD toggle to set how angles are interpreted.
Tips
- Chain operations freely:
2 + 3 × sin(30). - Use
^for exponents and√for square roots. !computes a factorial, e.g.5!= 120.
Frequently asked questions
What functions are supported?
Basic arithmetic plus sin, cos, tan, natural log (ln), base-10 log, square root, powers (^), factorial (!), parentheses, and the constants π and e.
How do I switch between degrees and radians?
Use the DEG/RAD toggle. In DEG mode the trigonometric functions interpret their input as degrees; in RAD mode, as radians.
How do I calculate a power or root?
Use ^ for powers (e.g. 2^10) and the √ button for square roots. For other roots, use a fractional power such as 27^(1/3).
