This is like "making assumptions" without knowing about it.Using results that are not applicable in the given situation.For example, if I say "you have a deck of n cards", don't assume n=52 just because that's what a standard deck has. In general, don't interpret problems in a way that is convenient to get a simple solution.Example: assuming that a set of numbers are integers, when the statement to be proved made no such restriction.In an introductory course (like one where you learn about proof techniques) you should avoid doing this, unless you're relying on something that has already been proved during the course, or is basic enough to be considered prerequisite material. Technically in a proof one can rely on extremely complicated results, as long as they are properly described and cited.Claiming that certain steps are obvious or simple facts, when they are actually just as difficult to prove as the main result.Note that it is sometimes ok to assume something similar but weaker than what you're trying to prove, for instance with proof by induction. ![]()
