Even more complicated problems are solved in the same manner-using
automatic storage and retrieval of intermediate results. It is easiest to work
from the inside of parentheses outwards, just as you would with calculations
on paper.

(9 + 17).
(9 + 17 – 4).
(9 + 17 – 4) ÷ 4.
First solve for the
intermediate result of (6 + 7).
Then solve for the
intermediate result of (9 3).
Then multiply the
intermediate results together
(13 and 6) for the final
answer.
