What would you have two-digit number you do not put forth - after subtraction of the two components can only get numbers of 81, 72, 63, 54, 45, 36, 27, 18 or 9. Look - in the symbol table, all symbols corresponding to these numbers - the same. Naturally, the square provides exactly what you "put forth"
And that did not raise suspicions, the picture is constantly changing.
That's the whole secret.

Simple! I dont know how but the game knows at what symbol you are looking at,and it can guess it.Try to do a random number,remember the symbol and try it again with the same number,look at another symbol and it wont guess the correct symbol!
Sorry for my bad English

Sorry danieldane but i tried that and he can guess your number simply because every answer you have is a multiple of 9,if you look at the symbol page all multiples of 9 (other than 90) HAVE THE same symbol!!

Look, if you take a number N=10xa+b, where b is between 0 and 9 and a between 1 and 9. Ok?
So, you have (10a+b) - (a+b)=9a, right ? After that, look at the multiples of 9, they have all the same sign. When you have your result (ex: 12>1+2=3>12-3=9), which is a multiple of 9. The squirrel must just say these sign and he's right ! Understood, now ?

Woof4, look, if you take N=10a+b, where b is between 0 and 9, and a between 1and 9, you have :
(10a+b) - (a+b) = 9a. Ok? So, the result can only be a multiple of 9 : 9,18, 27, 36, 45, 54, 63, 72, 81, 90. After that, look at the signs in the table. You can notice that all the multiplies of 9 have the same sign. The squirrel has just to show this sign and he's right. You see, it's no magic, but mathematics.
