This process of entering numbers onto the stack and using numbers
fronr tlie stack during calculations underlies everything the HP 48
does. This apirroach 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 aii}^ otJier command.
Example:
Divide tlie ])revious result by 1.3. The numerator—tlie
result of the previous calculation—is already entered, so
von only need to enter the denominator and divide.

The next few examjdes use a keystroke-saving shortcut that you
haven't seen yet. When calculating with the stack, "mathematical”
keys, such as f+1, causes an automatic fENTER) before it executes its
action. This allows you to use the setpience. 8.9 f ENTER) 7 -.2 0 inst.ead
of 8.9 [ENTER) 7.2 [ENTER) 0, 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.
