The resulting screen is the following:
Evaluating a sub-expression
Since we already have the sub-expression

highlighted, let’s press
the
@EVAL
D
soft menu key to evaluate this sub-expression. The result is:
Some algebraic expressions cannot be simplified anymore. Try the following
keystrokes:
—D
. You will notice that nothing happens, other than the
highlighting of the entire argument of the
LN
function. This is because this
expression cannot be evaluated (or simplified) any more according to the
CAS rules. Trying the keystrokes:
—D
again does not produce any
changes on the expression. Another sequence of
—D
keystrokes,
however, modifies the expression as follows:
One more application of the
—D
keystrokes produces more changes:
