Calculating on the Casio cfx-9850G Plus

0. START/END/EXIT

Press AC

/ON

1 to start (in RUN mode) and SHIFT AC

/ON

(i.e. OFF) to turn the calculator off. The

calculator will turn itself off after an inactive period, but nothing is lost when this happens. Just turn it

back on. If at some stage you are stuck, and can’t see how to recover, EXIT may allow you to start over.

1. SCREEN CONTRAST

The screen can be adjusted to suit you. Press MENU E (use the cos key for E: note the small pink letter

E just above it.) to access the CONTrast area. Use the and cursors to select colours or the screen

contrast; press the and keys to adjust these. Alternatively, press the F2 key just below the word

A on the screen to initialise all settings. Press MENU 1 to return to RUN mode.

2. SYNTAX

Calculations are performed by constructing an expression, in conventional algebraic syntax, and then

pressing EXE . Note that there is no equals key. Brackets are used when necessary. Some examples of

acceptable syntax include the following, each of which is different from the equivalent on most scientific

calculators, but is similar to the way expressions are conventionally written. Try each of these on your

calculator, and observe both the screen display and the final result. It is not necessary to clear with AC

/ON

before each new calculation. Don’t forget to press EXE .

EXE for log

EXE for 2(5

– 1) (Note multiplication sign is optional)

SHIFT EXE for 4

-1

(Note the yellow x

-1

above the key.)

SHIFT EXP EXE for 5sin 3π (Note multiplication signs are optional)

EXE for 3

EXE for (-2) – (-3) (Note the use of and keys.)

SHIFT EXE for 3 (Note the yellow √ above the key.)

SHIFT EXE for -3 (Note the result is given as a complex number.)

SHIFT EXE for e

(Note that ^ is not used here.)

b/c

+ A

b/c

EXE for 2/5 + 3/4

F–D F–D toggles last result between fractions and decimals

3. SET UP

Press SHIFT MENU to access the SET UP options. Use the and keys for highlighting options and

the function keys ( F1 , F2 , .. ) to select choices. Note that Angle can be set to degrees, radians or grads.

The format in which numerical results are given is controlled by Display. Press EXIT to return.

4. SUCCESSIVE COMMANDS

The screen will allow you to construct lengthy expressions if you want. Chain calculations are also

permitted. The result of the most recent calculation is recorded as Ans. This result is used in chain

calculations. It can also be directly recalled using . For example, try the following key sequence,

and note carefully the screen and the successive results to see what is happening:

EXE

Various constant operations can be performed by taking advantage of the fact that EXE repeats the

previous entry. For example, note the effect of the following key sequence:

EXE EXE EXE ...
