OK, I'm a very logical and mathematical individual, and cannot figure this one out. This is freaking me out quite a bit, as I cannot explain it. Do it several times, and if you know what's going on here, please let me know.

Don't read any posts below, or it will spoil the fun :)

its not very accurate.... i tried a few times i na row and it was right only part of the time, also you should notice the symbols are not in the same place each time

check your math...it will always be right :)
take a number, add the two digits, subtract that total from the original number.

oh i checked my math..... and if you do it right (pick the right numbers) you can fool it, it did work 2 out of 3 times....

Couldn't get through on the link (must be busy), but if you do a few math problems, it is easy to see how it works. Try doing consecutive numbers...ie. do 79-> 7+9=16 79-16=63 78-> 7+8=15 78-15=63. This works to 54 on others and so forth. Now the symbol next to each of those just has to be the same. Sorry to spoil it for some, but I love problem solving. (C:

I stand corrected to my math problem above.... I was wrong... so i plugged the numbers int o excel and came up with this....
there are only 9 possible answers to the problem....
when you add up any of the 2 digit numbers and subtract it from the orignal 2 digit number you will come up with one of the following numbers
9
18
27
36
45
54
63
72
81
if you look at each of the numbers above they each have the same symbol

| Don't any of you know your nine times tables? :P |

yes I do... NINE x TABLES = 2478 , or 1680 if you only had one table :P

I think you can use the nines table for any kind of psychic thing when it comes to numbers...it's the fact that no matter what number you multiply by 9, the result's digits will most likely add up to 9, except for some which add up to 18 (rare and only with larger numbers).
...maybe they call it the rule of nines...

Not only that! Look at the progression of the numbers (especially if you put 90 on the end of the list jab posted). They go up to 45 then the digits reverse and run back the other way.
My 4th grade teacher pulled the blinds in our class and locked the door one day, and told us he was going to share a secret with us. We weren't allowed to tell anyone else. Then he went on to describe these two properties of the 9 times tables (that weird progression and the way the digits add together). I was completely sucked in! I've never forgotten it.
I think it must be a property of counting in base 10. I'm not sure though. Does anyone feel like testing whether this happens with, say, the number 4 under base 5?

The results of the addition of the digits won't always come to 9 when you multiply by 9, but if you add the results of those results digits, and then those, and then those, they will all eventually come to 9.
6842168465171x9 = 61579516186539
6+1+5+7+9+5+1+6+1+8+6+5+3+9 = 72
7+2 = 9
