Well I will be darned! I tried it 5 times and it was right every time. How the heck do they do that??? Thanks for sharing.

It got me!

I figured it out. The the sum of the digits is divisible by 9

Ex. 9728

7829

--------

1899

1+8 + 9 + 9 = 27/9 = 3

Ex. 4312

1234

-------

3078

3+ 0 + 7 + 8 = 18/9 = 2

I knew there was a mathematical reason!

I was going to post the solution but Jerrye beat me to it.TBone

HOW DOES THIS WORK!!!!!!!

OH GOSH THAT WAS WIERD

Sorry Jerre,

Though I don't know the solution, you did not solve it. (I know, picky, picky, picky! )

Take your first example:

Ex. 9728

7829

--------

1899

the instructions were to circle one of the numbers in the answer, then type the other numbers in (in any order)

So circle the 8, leaving 1, 9, 9

I don't know what math it does, but some how it comes up with an 8 from those 3 numbers. So math experts, put on your thinking caps and figure it out for us!

Good Luck

Okay, hear goes... I did not finish the explanation....

The remaindar is 1899. Circle the 8 add 1 + 9 + 9 = 19; (y)

The sum of all of the numbers is always, 9, 18 or 27 ( a number divisiable by 9)

if y < 9 then

x = 9 - y;

else if y < 18 then

x = 18 - y;

else

x = 27 - y;

Geez, you guys! Don't you know Houdini magic when you see it? Why ya gotta analyze it??

Brother...after this, I'll be wondering if my dirty jokes will end up with an anatomical blow-by-blow (well, some of 'em might! LOL)

Chill, folks, OBVIOUSLY there's a trick and it's a mathematical formula... Those with smoked brain cells will be burnin' what's left trying to figure it out - let's just call it "magic" and leave the man behind the curtain....

Sorry,

I am a programmer, I have to analyze a trick involving numbers....
