5. USING MENUS

The Casio-9850G Plus is menu-driven, which explains why the keyboard is relatively uncluttered. For

example, many (powerful) functions are located in the (heirarchical) Options menu. Press OPTN and

you will see several menu names displayed. Press F6 to scroll through other menu names. Press the

corresponding F key (underneath a menu name) to access a menu. A menu stays on the screen until

you press EXIT .

To access a menu command, press the associated F key. Conventional syntax is used so that

generally you construct an expression as you would write it on paper. To leave a menu without selecting

a menu command press EXIT , which backs up one step. Press F6 F3 to select the PROBability menu

and try the following examples of some of the menu commands:

F1 EXE for 7! = 5040

F3 EXE for

= 1365

F4 EXE EXE EXE for successive random numbers on (0,1)

F6 F1 EXE for standard normal probability distribution, Prob(z ≤ 1) ≈ 0.84134

EXIT EXIT to return to the home screen.

Using many commands requires a knowledge of calculator syntax. For example, in the CALCulate

menu, press F6 F3 to select Σ( and then, using the X.θ.T key for X, construct the expression

Σ(X

,X,1,10). The comma key is below the cos key. Press EXE to get the sum of the squares of the first

ten integers.

6. MEMORIES AND VARIABLES

Memories are named alphabetically, as if variables are being given values. Store in a memory by using →

followed by and the relevant pink letter key. For example, to store 5 in memory R, press →

EXE . (Note the letter R is just above the key.) In addition to memories A to Z, there are memories

r and accessed via the and keys. Memories are recalled by first pressing the key. The

exception is memory X which can also be recalled using the X.θ.T key. Give M the value 3 by storing 3

in memory M and then note the effects of commands like the following:

EXE for 5R (Multiplication sign is optional.)

EXE for RM. (Multiplication sign is optional.)

EXE for 3R

M (Multiplication signs are optional.)

EXE for R

+ M

You can use the same key to store up to six ordered lists of values. Eg., {1,2,5} → LIST stores the

three values (1,2, and 5) into List 1. Use SHIFT and or for curly brackets, OPTN F1 F1 to get the

List command. The comma key is below the cos key.

7. EDITING COMMANDS

A command can be edited before EXE is pressed by using the and keys. Move the cursor to the

thing you want to change, and then write over it by pressing the desired keys. The and INS ( SHIFT

) key allow you to delete or insert items. Move the cursor to the right spot first. You can execute a

command at any time by pressing EXE . It is not necessary to return the cursor to the end of the line.

After pressing EXE , the immediately previous command can always be recalled by pressing or

. This is rather handy when a succession of values of a complex expression are sought. For example, if

you have just found 18(1.02)

with the key sequence , to then evaluate

18(1.02)

the following is sufficient:

, and

will then evaluate 18(1.02)

, and

will then evaluate 18(1.05)

, and so on.

Finally, press AC

/ON

and then ... for ‘deep recall’ of previous commands to edit.
