Figure out how this works:

before it totally freaks you out...

hey, i guess something is wrong, coz 4 out of 5 times, the answer was wrong

[zeroth]

mercury element, i think you did something wrong...
it'll always guess your symbol...

for any two-digit number, when you add up each integer and then deduct it with the 2-digit number, you'll always arrive to something as a multiple of 9, i.e., 9, 18, 27, 36, etc...

in the flash, the symbol is all the same for the multiples of nine. you may only be amazed because the symbol on the 9's sequence changes each time.

rock hard eh?

ya, i guess i did something wrong

good night

10a+b -(a+b) = x = 9a

Old, old, old.....

Chilling. Every time I did calculate the number it guessed right. If I pushed the button without calculating it guessed wrong. Sounds like it has a camera eye prying into my house! How does it do it?

Valencia, for your reference:

there's another one...www.mysticalball.com

also works on the same principle (or should I say formula? ).

Sorry for my stupidity. I tried again on the site posted by Max and it still got the sign I had in mind. When I looked for the sign, I looked first at one other than the one I had in mind, then the number I had in mind. I didn't move the cursor lest it had a clue. I just don't get it why every time it got it right. Does it really read my mind?
