let the magician read your mindChoose a four didgit number write that number backwards divide the smaller number by the larger number, keep your answer, now choose a nummber between 1 and 100, times your previous answer by the answer you just got, put a circle round a non zero number in other words put a circle round a number that isnt zero, type out your answer and put a * for the number that you put a circle around. for example if you got 145098 and you put a circle around the 5 it would be 14*098, remember to put a * for the number you put a circle around so the magician (me) dosnt know what that number is, reply to this topic as soon as possible, once you have replied i will tell you what that * number is! have fun and enjoy!! Theres no other place like home or is there.............. #2 20070225 07:09:32
Re: let the magician read your mind
I think you made a mistake – I think you mean subtract the smaller number from the larger number. Also, I think the digits of the number must not all be the same (i.e. it must not be 1111, 2222, etc). #3 20070225 12:46:02
Re: let the magician read your mindYes, I think you're probably right. That would certainly explain why only nonzero digits are allowed to be chosen. Otherwise, if a zero was chosen then the 'magician' wouldn't be able to tell whether it was a 0 or a 9. Why did the vector cross the road? It wanted to be normal.
