The question was; if you have a rectangular piece of paper and fold it so that there’s an extra centimetre on one side and then you fold it the other way with a centimetre extra on the other end, then how far in millimetres would it be between the two creases when the paper is unfolded?
It’s a simple, easy question and the game gave me three spaces to write a number into. I quickly scribbled my answer down; 100mm and was told that was incorrect. Baffled, I got a piece of paper out and tried it out – measuring the gap as one centimetre. Again I put my answer in. Again; incorrect. It was only on the third go that I slapped my face and realised that there were only 10 millimetres in a centimetre – not 100. I was being a moron and had been led astray by the fact that the game gave you three spaces to put an answer in, not two. I’m an idiot.
That then got me thinking (as best as I was able anyway) about how my brain is stuffed with useless information that I use everyday and all the actual useful stuff that I never need to know has trickled away over the years. It’s ironic and twisted, but I can get more use out of game memory than I’d ever get from remembering how to do trigonometry properly.
