Appendix B
Algebraic Mode (ALG)
Although most of this material is included at the appropriate places throughout this
manual, it is collected here for easy reference.
To select algebraic mode, press
f[
. When the calculator is in algebraic mode,
the
ALG
status indicator is lit.
Note:
In ALG mode, it is a good idea to begin calculations by pressing
OO
. This will ensure that there are no pending arithmetic calculations
that might interfere with the solution of a new problem. The reason this key is
pressed twice is that pressing it the first time clears the display and X-register
only, allowing you to correct an erroneous entry by keying in a correct
number. The second press of
O
will clear any pending operations as well.
Pressing the
}
key is another way to ensure that there are no pending
operations before beginning a new calculation.
Simple Arithmetic Calculations in ALG Mode
