I've been staring blankly at page 37 for a couple of days now trying to figure out what step to take next in building the ALU. I seem to be stuck.

I saw a Logisim schematic posted in a thread around here and was trying to follow along, but I feel like that's cheating myself out of figuring it out.

Any tips? I've completed all the prior chips for this and the last chapter.
