Remember. This method of entering numbers, called Reverse Polish
Notation, is unambiguous and therefore does not need parentheses.
• You never work with more than two numbers at a time.
• Use Ienter I to separate two numbers keyed in sequentially.
• Pressing a function key immediately executes that function.
• Intermediate results appear as they are calculated, so you can check
each step as you go.
• Intermediate results are automatically stored. They reappear auto
matically as they are needed for the calculation—the last result
stored is the first to come back out.
• You can calculate in the same order as you would with pencil and
paper.
