Operating Modes

This calculator has five operating modes to perform various operations. These modes are selected from the MODE key.

Selecting a mode

1.Press b.

The menu display appears.

Press d to display the next menu page.

<MODE-1> ƒNORMAL ⁄STAT ¤PROG ‹EQN

<MODE-2> ›CPLX

2.Press 0 to select the NORMAL mode.

•In the menu display, press the assigned number to choose or recall a selection.

What you can do in each mode

NORMAL mode:

NORMAL MODE 0.

Allow you to perform standard scientific calculations, Differential/Integral functions, N-base calculations, Solver function, Simulation calculation.

STAT (statistics) mode:

Allows you to perform statistical calculations.

PROG (program) mode:

Allows you to create and use programs to automate simple or complex calculations.

EQN (equation) mode:

Allows you to perform equation solvers, such as quadratic equation.

CPLX (complex) mode:

Allows you to perform arithmetic operations with complex numbers.
