5 people have thought of different number seven times in a row... and this internet orogram got it right everytime...

at the beginning of the term they ask you to add smth to the number you think of and at the and they tell you to substract the number from that term... so in the end it doesnt matter what number you chose ;)
example, if you think of nr 5 the term could be:
5+30+19-16-29-4-5 so actually everything you calculate is 30+19-16-29-4 so its not hard for the program to guess the result
