Casio CFX-9850GB PLUS Getting Started page 4

The CFX-9850 GB PLUS has identical capabilities to that of a scientific calculator. It
has a keyboard almost identical to that of a scientific calculator. All those operations
performed on a scientific calculator can be accessed using the RUN mode (MENU
1). To complete a calculation, first type an expression into the command line and
press the blue EXE key to execute the command. The EXE key (located in the
bottom right hand corner) replaces the '=' key on the scientific calculator.
♦ The yellow SHIFT key enables the user to access the yellow (secondary)
functions located above the calculator keys.
♦ Casio Scientific and Graphic Calculators use S-VPAM (Super Visually Perfect
Algebraic Method), that is 'how you say / write it, is how you enter it'. For
example, the square root of 12 is entered by SHIFT then X
√12.
♦ The power (exponentiation) function is accessed using the ∧ key (next to the EXIT
key. For example, 2
♦ The (red) ALPHA key will allow you to access the red secondary functions.
♦ The F↔D key converts a fraction to a decimal or a decimal to a fraction once a
calculation has been completed (non terminating decimals are not included!).
The Run Mode
Enter into the RUN mode from the main menu by using the arrows to highlight the
RUN mode then press EXE, or from the main menu simply press 1.
Because the calculator has been reset, it has returned to its initial default settings. To
examine the default settings of the RUN mode press SHIFT then MENU (SETUP).
Notice, for example, that the default setting for an angle is currently radians. Scroll
down the screen, using the arrows, to highlight Angle. At the bottom of the screen
you have three options for Angle:
Press the F-key that corresponds to degrees (i.e. F1) and note that the option has
now been changed on your screen. Press the EXIT key, then enter 10cos60 and
press EXE.
