All I can say is fuck and fuck again ... how does this work? When I was messing around it was wrong. When I played for real it hit right first try both times, very scary .

[ted]

I did it 4 times and it was right every time. The first time I put the mouse on the number as I was thinking, but I made sure the next three I didn't move anything on the computer. Really scary

Tt works by casting out 9's. When you add the 2 numbers together and subtract from the original you always get number divisible by 9. All the 9's have the same sign. I think this is how it works.

You tellin' me it's not little rays coming out of the computer and reading my mind? Damn!

[ted]

But mine were 4 different signs, not the same one

[dick_nyc]

I didn't say that the numbers divisible by 9 always had the same sign. I said that each time you ran the program all the numbers divisible by 9 were the same sign. If you look at the numbers the signs changed each time you ran the program. Therefore the sign for the 9's would be different each time, but all the 9's would have the same sign. Check it out.

True, each time you use the "phychic ball" it gives you a different screen with each number having what looks like a random symbol associated with it. But, if you look at the screen closely before you click the crystal ball, all fators of 9 (9, 18, 27, 36, 45, 54, 63, 72, and 81) have the same symbol next to them. Then, when you choose any two digit number, add the digits together and subtract the sum from your original number, you will always end up with a factor of 9. Using a little algebraic proof, here is why:

 

Take any two digit number, for example, 34. You can represent this number using variables as 10x + y with x = 3 and y = 4. So, the expression 10x + y can now represent any two digit number.

 

Then, when you add the digits together, you get 3 + 4 = 7, or using the variable expression, x + y.

 

Next you subtract this sum from the original number, like 34 - 7 = 27, or using the variables,

10x + y - (x + y) = 9x.

 

Therefore, you can see that your answer is always a multiple of 9 no matter what two digit number you start with and since the list of seemingly random numbers and symbols has the same symbol associated with all of the factors of 9, then the computer always gets your symbol correct. (Unless you add or subtract incorrectly, of course!)

 

Very neat trick, huh? And who says math isn't fun?

Thanks for the mathematical explanation. I knew how it worked, but I haven't done any algebra for 45 years and didn't want to enter the murky world of mathematical expressions at this time. Nice posting.

Nice posting.

 

Thanks, Dick_nyc, or Rhomp2002 - which ever name you would like to go by! Glad I could help!

Aaron, thanks for putting it terms that even I could understand. Your explanation was fantastic.

 

Glad to know there's more to you than just a fit and hunky body!
