check this out. if anyone has a credible explanation for how this works, let me know... freaky.

The formula is take any 2 digit number, add its two digits and substract it from the original number. So start with AB AB-(A+B)= So every number from 10-19 will yield an answer of 9. 10-(1+0)=9 etc.. Every number from 20-29 yields 18. Every number from 30-39 yields 27 etc.. So, if you set up your table with 9,18,27,36,45,54,63,72,81 all having the symbol associated with them you can't miss. The rest of the table can be random symbols since you will never end up on any of those numbers. The only extra trick is that the table shuffles the symbol associated with 9,18,27,36,54,63,72,81 each time you reload the page. Thus everytime you try a new number you get a new symbol and the computer seems to keep getting it right unless you make an error in your arithmetic

you did indeed, and in a way that was much more elaborate than mine...I just said "the symbol that shows up comes from an answer that adds up to 9". You damn PhDs!

XY is (10X + Y)

so the calculated number is (10X+Y) - (X + Y) = 9X

All the multiples of nine are the same symbol.
