Paul's puzzle 37 solution - 36 parts


Here’s my solution (it’s the one from the book):

And here’s the link:

Description: This solution adds numbers by counting down on the left register while right register counts up.

This is actually not the most efficient way to add numbers, but conceptually it is the easiest to understand. Puzzle 47 uses a more efficient method.


I’m not sure if I’m disappointed or excited when the answer I have (exactly) replicates the answer in the book.
This is exactly what I got!
