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.
