www.casioeducation.com
Selecting the RUN-MATRIX icon will allow you to
perform general computations and arithmetic.
The lkey executes operations. When data is
entered, the lbutton must be pressed to store the
data.
The zkey is used to obtain a fraction bar. To obtain
a mixed number, press zafter inputting the whole
number.
The Okey will power the unit on. To turn the unit
off, press the yellow Lkey, then Okey.
The xkey is a toggle key that will change answers
or entered numbers back and forth from decimal to
fraction form.
The dkey operates like the back arrow on a web
browser; it will take you back one screen each time
you select it. The dkey will not take you to the icon
menu.
The pkey displays every mode the calculator has.
To select a mode, you may $B to the desired icon
