I'm still having trouble wrapping my head around this. I'm lost at syntax usage, what chips to use, and how to even start. My first instinct is to use mux for the if-then statements but I don't know how to incorporate all of the inputs into my code. I also have no idea what the zr and ng outputs mean in context of this whole thing other than zr being True if out=0 and ng being true if out < 0.
