How to use

  • Click buttons or use your keyboard — numbers, operators (+, -, *, /), Enter for equals, and Escape to clear.
  • Toggle DEG / RAD to switch between degree and radian mode for trig functions.
  • Use ANS to insert the previous result into the current expression.
  • Scientific functions like sin, cos, log, and √ require a closing parenthesis — e.g. sin(30).
  • raises the current number to a power — e.g. 2^(10) = 1024.
  • AC clears everything; deletes the last character.
  • Calculation history is shown below the display.
