Can you explain how this works.?

This is obviously a mathematical trick but can you figure how it works ??~~click on this link for the website.~~

Yeah it's a mathematical trick, based on the number nine. Check out the symbol on all the multiples of nine 9,18,27,36,45,54,63,72, and 81 and all other numbers don't happen.Can you explain how this works.?
The answer is simple!


when you start with 2 numbers minus the 2 added together. answer is one of 15 possable answers! they are 0 -6 -9 -18 -23 -27 -29 -36 -40 -45 -54 -72 -73 -81 -82


if you look at the symbols they are all the same on these numbers. each time you play they just change the symbol.
I think I did. Most of the results you can get are the exact same. Example: you pick 99. Add the digits (18) and subtract from 99 (81). Now look at 98. Add digits (17) subtract from 98 (81) That tells me something right away.





Other numbers: 15. Add digits (6) subtract from 15 (9). I bet you 81 and 9 have the same symbol posted. That symbol will be the card flipped.
If you add up the digits of any two digit number and subtract it from the original, you always get a multiple of 9.





81; 8+1=9; 81-9=72; 72/9= 8.


55; 5+5=10; 55-10=45; 45/9=5.





So they make the symbol all the multiples of 9 and mix them up to confuse people. So they mix up the symbols after each round, but the winner is always a multiple of 9
That's pretty cool. It took me a few times to figure it out. It really made my girlfriend laugh. Unfortunately there is no magic here , just some very clever coding. It's a java script program and if you notice... the values and symbols change each time you try again. That's because the probability of the final answer only works out to be a certain set of #'s. The code just changes the symbol each turn to represent only those #'s that could be correct.
like the guy on top said
I dont kno but that little thing read my mind!!!!!
