In computability theory, an undecidable problem undecidability in number theory book pdf is a type of computational problem that requires a yes/ no answer, but where there cannot possibly be any computer program that always gives the correct answer; that is, any possible program would sometimes give the wrong answer or run forever without giving any answer. This question can address any given equation, but in the true spirit of mathematics, it can address a general situation.
