Chain Calculations

The automatic lifting and dropping of the stack’s contents let you retain intermediate results without storing or reentering them, and without using parentheses. This is an advantage the RPN stack has over algebraic calculator logic. Other features of RPN include the following:

„You never work with more than two numbers at a time.

„Eseparates two numbers keyed in sequentially.

„Pressing an operator key executes that operation immediately.

„Intermediate results appear as they are calculated, so you can check each step as you go.

„Intermediate results are automatically stored. They reappear automatically 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－that is, from the innermost parentheses outward:

4 ⎟ [ 1 4 ＋ ( 7 x 3 ) － 2 ] ＝ 0 . 1 2 can be solved as 7 E3 *14 +2 -4 x/
