Here are a few I recall from that age: Well my first (and easiest) question was to find all integer triples (x,y,z), and where n is an integer > 2, such that $x^n + y^n = z^n$ A slightly tougher one was: Prove that the set A defined as $\{ z | z \in \mathbb{C}, \zeta (z) = 0, \zeta (s) := \sum 1/n^s \}$ is a subset of the set B-union-C, where B defined as $\{ z | z = 0.5 + xi, x \in \mathbb{R} \}$ and C is defined as $\{ -2n | n \in \mathbb{N} \}$
