In this series, we'll look at plenty of examples of natural deduction in propositional logic. There is a much more precise way to formulate all of this: at some point, I plan to give a precise definition of everything I've been doing in this video. However, for now, we'll just focus on proving some simple statements in natural deduction to try ...
