4 Scientific Calculator FAQ

Q. Does this calculator evaluate in Degrees or Radians?

Both! You can switch between DEG and RAD mode using the toggle button above the display. Degree mode is selected by default for everyday math.

Q. Can I type complex nested expressions with parentheses?

Yes, you can write nested expressions like sin(45) * (2 + 3^2) and the calculator will evaluate them following proper mathematical operator precedence.
