ahhh fucking i-rules. and fucking modus ponens. ahhhh

I'd like to discuss logic all weekend and get back to our other shit next week. I really need to understand this better.

I don't get how to make a counterexample from the other material and the sound/valid parts of it. Can you draw me up some examples and give me a small quiz thing?

Thanks buddy

You prolly have a book or something. Ask me questions from there.

I'll do it from memory because I don't see anything in the book.

So (A ^ B) <-> C)=1 A=1 B=1 C=0 so (1 ^ 1) is 1 then (1 <-> 0) is 0 so it's false. This is a valid argument as it's opposite from the conclusion in comparison to if it was the correct conclusion which would make it invalid right?

How would I find the counterexample for that?

If you can respond to others, you can respond to me.

Ask more descriptive questions.
