Calculator resources

Choose your calculator model below for official instructions and worked tasks. Check whether your paper allows a calculator before using it.

• Casio fx-991CW

  Scientific calculator with no symbolic algebra or graph plotting. Numerical integration does not demonstrate an exact antiderivative. A calculator output does not supply required reasoning.

• Casio fx-991CW+ UK

  Consult the manual for this exact UK model. Do not assume every screen or menu matches the original CW.

• Casio fx-CG50

  Not a computer algebra system. Model and OS matter; a graph may hide roots or discontinuities outside the viewing window.

• Casio fx-CG100

  Menus differ from the CG50. Use model-specific instructions rather than copied keystrokes.
