Magic Gopher

Instructions: 

Think of a number with two digits. For example 43.

Now add the two numbers together. For exammple 4 + 3 = 7.

Next, subtract the new number from your orginal number. For example 43 - 7 = 36.

Finally, look at the symbol next to your number. Remember it.

Now the Magic Gohper will read your mind and tell you what your symbol is. Watch carefully.

Of course he gets it right. You subtract the two nubers added from the original number. Example: 43. You subtract 4+3. Instead of taking 43-7, take 43 -3 -4. You will get the same answer. However this proves that no matter what nuber you choose you will always subtract the second number (in this case 3) to get a number that ends with 0 (in this case 40). Then the nuber you subtracted second can only be 1, 2, 3, 4, 5, 6, 7, 8 or 9 And the only possible outcomes will be, 90 - 9 = 81, 80 - 8 = 72, 70 - 7 = 63, 60 - 6 = 54, 50 - 5 = 45, 40 - 4= 36, 30 -3 = 27, 20 - 2 = 18 and 10 - 1 = 9. You might notice that all of these numbers are in the 9's multiplication table. That is because when multiplying by 9 you can instead multiply by 10 and subract the other number. For example: 5*9 = 5*10 - 5 = 50 - 5 = 45. First you add one 5 and then you subtract it again. 9*5 = 9*5 + 5 - 5.

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!!
