        Yeah, I think the point is that the person answering was wrong/over complicating. If x=10i, then x^2 would be -100 (or potentially -10 depending on what you think the ^2 is applied to).

        Depends on what are the allowed values for x are. Real numbers, complexe numbers, binary or I made up my own numbers ;)

        Probably what they were going for, but there are literally an infinite number of exotic arithmetic spaces you could ask this question in. For example, x=10 works in any ring with a modulus greater than 100 and less than 1000.

          fortunately math problems are administered in the context of the class, so it will be pretty obvious that it’s in the complex plane.
