2. You could try Twelf. It is based on a more high-powered dependent type theory, but first-order logic can be encoded in a few lines (included in the examples directory), letting you write natural deduction proofs as lambda terms. You can also have a look at this short axiomatization of ZFC set theory. Share.

We can also simplify statements in predicate logic using our rules for passing negations over quantifiers, and then applying propositional logical equivalence to the “inside” propositional part. Simplify the statements below (so negation appears only directly next to predicates). ¬∃x∀y(¬O(x) ∨ E(y)). ¬∀x¬∀y¬(x < y ∧ ∃ ...3. Symbolic Logic and Proofs. Logic is the study of consequence. Given a few mathematical statements or facts, we would like to be able to draw some conclusions. For example, if I told you that a particular real-valued function was continuous on the interval [0,1], [ 0, 1], and f(0)= −1 f ( 0) = − 1 and f(1)= 5, f ( 1) = 5, can we conclude ...Here is a sketch of what you need to do in order to get you going. When proving ¬ ¬ ∨ ¬) from ∧, assume ¬ ∨ ¬ and try to arrive at a contradictions. This should be quite straight forward by using ∨ elimination and the fact that ∧ is already known. ∧ from ¬ ¬ ∨ ¬, first assume ¬ then get a contradiction using ∨.Boolean Algebra Calculator.
