DS8, doing an ALEKS topic on equations involving logarithms, gets a "Your answer is incorrect", which it is, because his calculation has given him a spurious solution (one that would have made the original equation involve the logarithm of a negative number), and he has entered it without noticing.

Me, perhaps slightly patronisingly: Remember, you can't take the logarithm of a negative number.

DS8, more patronisingly: Well, you can in fact, it's just that the answer is complex.

He has met Euler's identity, but we're confident that nobody, and no book, has ever talked to him about anything closer to this statement than that.

How's that for a wibble-brag?!
