The first choice you need to make is the style of entry. The
three types are:
Textbook
•
An expression is
entered in much the
same way as if you
were writing it on paper (with some arguments above
or below or others). In other words, your entry could
be two-dimensional, as in the example above.
Algebraic
•
An expression is
entered on a single
line. Your entry is
always one-dimensional.

Notation). [Not available in CAS view.]
The arguments of the depression are entered first
followed by the operator. The entry of an operator
automatically evaluates what has already been
entered. Thus you will need to enter a two-operator
expression (as in the example above) in two steps, one
for each operator:
Step 1: 5
