Oops – in my head I just had EXP = 50 instead of EXP = 50 * 50. Well, in any case that would make it be 500. Not the 200 you for whatever reason expect.
However, comments like
I find it funny that you claim to be a mathematician but get these simple things utterly wrong.
show me I don't need to waste any more time trying to understand horrible code. It's fascinating what attitude people have towards others who try to help them for free(!). I don't need to prove to you that I studied mathematics, just as I don't need to listen to you accusing me of lying. Maybe others will continue to help you, although I certainly don't hope that they will.
