Proof calculator logic.
That would make it a tautology. Since what I want to prove is a conditional, I assume the antecedent, (P → Q) ∧ (Q → R) ( P → Q) ∧ ( Q → R) as the start of a subproof, indented in Fitch-style natural deduction. Since this antecedent is a conjunction, I use conjunction elimination (∧E) to derive each of the conjuncts on lines 2 and 3.

In propositional logic, the deduction metatheorem gives you a procedure to convert (a fair amount, at least) natural deduction proofs into Hilbert style proofs, given that the Hilbert system has. 1) CqCpq as a theorem or an axiom schema, and. 2) CCpCqrCCpqCpr as a theorem or an axiom schema, and.
To solve this using an indirect proof, assume integers do exist that satisfy the equation. Then work the problem: Given: Where a and b are integers, 10a + 100b = 2. Prove: Integers a and b exist. 10a+100b=2 10a + 100b = 2. Divide both sides by 10: a+10b=\frac {2} {10} a + 10b = 102. Wait a minute!

E.g. chapter 13 of Paul Teller's logic textbook contains a description of such a procedure for propositional logic (basically truth trees in Fitch notation). Also, first order logic is semidecidable, meaning there are ways to mechanically find a proof if the sequent is valid (though the search may never terminate in the case ...Suppose we want to prove that.
