THIS ONE WILL BLOW YOUR MIND!





I know there must be a very logical answer to this, but so far can't figure it out. Can you??





This came to me from a guy who has two masters and one doctorate degree and was a former instructor at the Naval Academy and he couldn't figure out how it was done. So don't write me back asking how they do it.... THIS IS GREAT, TRY IT!!!!!





Can you figure out how this works?





1) Go to the link below. After reading each window, click on the boy in the lower right corner of the picture.





2) In the last window type in your answer in the white box using the Keyboard (there is NO cursor).





3) Watch the paper in the boy's hand. You will be amazed. And no, I don't know how it's done. Click here:

I believe the answer is this...A number subtracted from a larger number containing the same digits in a different order will produce a number whose digits will add up to 9 or a multiple of 9. Therefore it's easy to figure the digit that is left out because it would be the smallest number added to the other digits to produce 9 or a multiple of 9.


Ex: When I subtracted the smaller number from the larger number I got 873. 8+7+3=18. Leave off any one of these digits and the program subtracts the other two from 18 and gets the number you left out.
