Basically i live in UK but my origin is Albanian, and as i was for holidays on my country, i saw a very interesting video about a very intelligent man who was ready to calculate up to 20 value numbers like 1750000 * 5710000 (Things like that) Faster than calculators. The sad truth is that, this guy is considered as a homeless and a stupid man. People on his village treat him as a funny object which solve any mathematical, chemistry or physic problems. I know that you won't understand the language but you may see the calculator on the video, and the numbers he says are all the same as the calculator show. I had a chance to meet this guy and YES he is completely a genius. http://www.youtube.com/watch?v=BA6gpajQM3Y&feature=player_embedded#!
