Calculates (7 x 3).
Calculates bracketed
numbers next.
Puts 4 before 33 in
preparation for
division.
Calculates 4 -5- 33, the
answer.
Problems that have multiple parentheses can be solved in the same
simple manner, using the automatic storage of intermediate results.
For example, to solve (3 + 4) x (5 + 6) on paper, you would
first calculate the quantity
inside these parentheses..
(3 + 4) x (5 + 6)
.. .and then the quantity
inside these parentheses...
.. .and then you would multiply the two intermediate answers together.
You work through the problem the same way with the HP-32S, except
that you don't have to write down intermediate answers—the calcu
lator remembers them for you.
