I actually got to hate math in grade 3 with such problems. Nobody explained to me that I could just write down an equasion, at least my father (physicist) could not. And all I saw in the magazines were cryptic answers like "it's plain obvious that for Jose-Rammstein conjuncture, x = 10"
I also met the problem #9 at an interview, and was asked to write the solution in pseudocode, as a kind of fizz-buzz test. (A peasant must take a wolf, a goat and a cabbage across a river in a boat. However the boat is so small that he is able to take only one of the three on board with him. How should he transport all three across the river? The
wolf cannot be left alone with the goat, and the goat cannot be left alone with the cabbage.)
