Problems that have multiple parentheses can be solved in the same manner using
the automatic storage of intermediate results. For example, to solve (3 + 4)
×
(5 +
6) on paper, you would first calculate the quantity (3 + 4). Then you would
calculate (5 + 6). Finally, you would multiply the two intermediate results to get the
answer.
Work through the problem the same way with the HP 33s, except that you don't
have to write down intermediate answers—the calculator remembers them for you.
