HP 48G Series User Manual

This
process
of
entering
numbers
onto
the
stack
and
using
numbers
from
the
stack
during
calculations
underlies
everything
the
HP
48
does.
This
approach
makes
it
easy
for
the
calculator
to
work
very
efficiently
because
the
results
of
one
calculation
are
left
sitting
on
the
top
of
the
stack
ready
to
be
used
by
any
other
command.
Example: Divide the previous result by 1.3. The numerator—the
result of the previous calculation—is already entered, so
you only need to enter the denominator and divide.
The next few examples use a keystroke-saving shortcut that you
haven’t seen yet. When calculating with the stack, “mathematical”
keys, such as (1), causes an automatic before it executes its
action. This allows you to use the sequence, 8.9 7.2 (=) instead
of 8.9 7.2 (2), to subtract 7.2 from 8.9. In short, it
saves you a keystroke.
Work the following short examples of stack arithmetic that use
the fourth-row mathematical keys. Notice in particular how each
operation leaves the results ready for the next operation.
