Logic Foundations With Haskell Haskell 2 Basic Operations

Summary

In this video we implement our own version of the type Bool, along with the We discuss how the foldr and foldl patterns can be used for very compact implementations. All code can be found in the course git ... We implement natural numbers, arithmetic and comparison using an inductive datatype. All code can be found in the course git ... I show how the Maybe datatype and lists can be used to deal with We cover types, type variables, and typeclasses in Andres Löh goes through the following We implement the typeclasses Ord, Enum, Num, Real and Integral for the natural numbers. This allows us to use all standard ... We cover the semantic definitions for propositional We implements datatypes for integers based in the natural numbers. Correction: At 04:50 I forgot the case (==) (Neg Z) (Pos Z) ... We prove completeness of the natural deduction proof calculus for propositional
