1) (ceebs tex)= (xy+xz+yy+yz)(not[x] + z) = (y(x+z+1)+xz) [as yy=1] = (x+y)(not[x] + z) [x+z+1 is always true]
2) SDD marker says we only need to know the basic laws of boolean - none of the XOR crap
3) how the f is there THREE inputs to AND?

1. Okay.

2. There was one in one of the trial papers.

3. Why not?

Come on guys, his textbook isn't all THAT bad. Sure it has some flaws but most of the content would be helpful to a SDD student. He has kids to take care of now which is probably why the textbook was released late in the year.

he works at the PEC - a coaching college i believe? :p he also writes independent papers from what i've heard.

there's one redeeming feature about sam davis: if you don't have any info on something, he'll have a million pages on it!

3) how the f is there THREE inputs to AND and OR? if it's what i think it is, boolean algebra is (abc) + d

Close. The solution is quite nice.

Hmm I'm with cyberbully here. AND is a binary operation. I guess it's shorthand for (a AND b) AND c, but I don't think that's a valid depiction in a circuit.

I've seen many Comp Sci textbooks use a three input AND gate. But yeah I guess that's quite true.
