Off topic and not related to the discussion;
I was filled with nostalgia when I read this. One of favorite my parts of Math back in high school (secondary school). I remembered the feeling of satisfaction whenever I got to the end of 'proving' a formula and could finally write QED. I absolutely loved those questions back then. Thanks for the pleasant memories
