Proof calculator logic.

When we describe the specification of a program or prove a certain theorem in modal logic, we need the \nec-modality in general, because \nec\ is needed for correctness proofs. However, the comonad types that model \nec-modality are not necessarily needed in the type system for the extracted programs, because “the …Subsection Direct Proof ¶ The simplest (from a logic perspective) style of proof is a direct proof. Often all that is required to prove something is a systematic explanation of what everything means. Direct proofs are especially useful when proving implications. The general format to prove \(P \imp Q\) is this: Assume \(P\text{.}\)Okay, so let’s see how we can use our inference rules for a classic example, complements of Lewis Carroll, the famed author Alice in Wonderland. “All lions are fierce.”. “Some lions do not drink coffee.”. “Some fierce creatures do not drink coffee.”.
