... • But, it’s difficult to see how to use a direct proof in this case. We could try indirect proof also, but in this case, it is a little simpler to just use proof by contradiction (very similar to indirect). • So, what are we trying to show? Just that x+y is irrational. That is, ¬i,j: (x + y) = i/j. ...

... is not enough to simply plug in a few numbers for x and check in those cases. Playing around with specific numbers may help you discover the proof, but it is not sufficient for the final proof write-up. In contrast, you can disprove a statement by finding a single example where the hypotheses hold b ...

... Let a  b = a + b + 4. Then a  k = a + k + 4 and if a + k + 4 = a, then k = -4. Consider k = 4. a  4 = a + 4 + 4 = a for all real values of a, and 4  a = 4 + a + 4 = a for all real numbers a. Hence if a  b = a + b + 4 , then a  4 = 4  a = a for all a  Reals.

To avoid paradoxes, David Hilbert (a significant German mathematician) proclaimed the program of formali ...

Turing's proof

Turing's proof is a proof by Alan Turing, first published in January 1937 with the title On Computable Numbers, With an Application to the Entscheidungsproblem. It was the second proof of the assertion (Alonzo Church's proof was first) that some decision problems are ""undecidable"": there is no single algorithm that infallibly gives a correct ""yes"" or ""no"" answer to each instance of the problem. In his own words:""...what I shall prove is quite different from the well-known results of Gödel ... I shall now show that there is no general method which tells whether a given formula U is provable in K [Principia Mathematica]..."" (Undecidable p. 145).Turing preceded this proof with two others. The second and third both rely on the first. All rely on his development of type-writer-like ""computing machines"" that obey a simple set of rules and his subsequent development of a ""universal computing machine"".
