I first read the chapter, and then was struggling to understand the problems, so I went back and read again, and I realized I don't quite understand Figure 1.6.

I read Appendix A, and I am still struggling.

It seems like a very complicated way to write out the Xor function, but I am sure there is a reason for its complication, and I just don't get it.

I don't understand how why the parts are done the way they are.

I tried a canonical representation of Xor that did not do it and I am lost.

If anyone could help, I would be really appreciative, I am STUCK!

Thanks!
