The system we will use is known as natural deduction. The system consists of a set of rules of inference for deriving consequences from premises. One builds a proof tree whose root is the proposition to be proved and whose leaves are the initial assumptions or axioms (for proof trees, we usually draw the root at the bottom and the leaves at the top). 76 Natural Deduction for Sentence Logic Let's illustrate this kind of thinking with a simple example. Suppose you are asked to derive 'B&C' from the premises 'A3B', 'A>C', and 'A'. Right off, you know that the derivation will take the form where you still have to figure out what replaces the question marks.

In natural deduction the flow of information is bi-directional: elimination rules flow information downwards by deconstruction, and introduction rules flow information upwards by assembly. Thus, a natural deduction proof does not have a purely bottom-up or top-down reading, making it unsuitable for automation in proof search.

Just keep plugging away.
