Subject: Fitch style natural deduction
Are we allowed to use fitch style proofs for our homework assignments, or does it have to be tree proofs?

It has to be a sequence of natural deduction rules, applied in the correct order to the correct formulas with clear demarcation which formulas are assumptions and where they are discarded :P

That's literally it. I always was confused with fitch style, because it was not clear to *me* what happened there. I assume a couple of annotations would be sufficient, but if someone has to *know* fitch-style nontation in order to read them, then they're not the way to go.
