Sixty-Sixth Journal Entry

I suppose I'm overdue for a puzzle, aren't I? I thought I'd try something different this time. Instead of giving the same puzzle to everyone, you can ask me for whatever kind of puzzle you'd like. I've found that my number puzzles don't go over very well, so a choice would be best, wouldn't it?

I'd be fine with any kind of puzzle!

[puzzledprof]

Surely you must have some kind of preference?

[battledancing]

Well, I like logic puzzles more than those involving math...

[puzzledprof]

How about this one?

Three friends are arguing about how many white fish are in a group of yellow fish.

The first says, "There are at least four white fish."
The second says, "No, there are less than four white fish."
The third says, "There is at least one white fish."

If only one of them is correct, which one is it, and how many white fish are there?

Luke usually gave me one now and again while I was laying in bed. Any puzzle is pretty entertaining, Professor.

[puzzledprof]

So you'd like one, then?

[shhsnacktime]

Of course. It helps pass the time.

How about this one, then?

If 8+1=2, 9+8=3, and 6-3=1, what is 8+8, using the same rules?
