I will assume that 4 is the desired conclusion. Then what we want to determine is whether the following is a valid deduction: T ∧ (T ⊃ ((B ∨ M)) ∧ (M ⊃ H)) ⊃ ~H. One could put this into a truth table generator. Here is the result using Michael Rieppel's Truth Table Generator: Proof solver (natural deduction) Watch.

Conversely, a deductive system is called sound if all theorems are true. The proof rules we have given above are in fact sound and complete for propositional logic: every theorem is a tautology, and every tautology is a theorem. Logitext is an educational proof assistant for first-order classical logic using the sequent calculus, in the same tradition as Jape, Pandora, Panda and Yoda.It is intended to assist students who are learning Gentzen trees as a way of structuring derivations of logical statements.

Enter a formula of standard propositional, predicate, or modal logic. The page will try to find either a countermodel or a tree proof (a.k.a. semantic tableau). The standard deduction is a set amount of money the state allows any taxpayer to deduct on their taxes, based on filing status and income. Itemized deductions are a set of deductions that may or may not apply to you.
