Chain Calculations in RPN Mode

In RPN mode, the automatic lifting and dropping of the stack's contents let you
retain intermediate results without storing or reentering them, and without using
parentheses.

Work from the Parentheses Out

For example, evaluate (12 + 3)
If you were working out this problem on paper, you would first calculate the
intermediate result of (12 + 3) ...
... then you would multiply the intermediate result by 7:
Evaluate the expression in the same way on the HP 35s, starting inside the
parentheses.
