Think of a number with two digits. For example 43. Follow the Magic Gopher's instructions and he will amaze you by telling you what number you chose.



He is Stupid Dog, isn't he? but another colour =))

how does that happen?????

There must be something wrong. I have done three tries so far but his guesses were wrong!!!!

oh,my god!he is right

i didn't read the explaination of others , because I would understand this joke. The dog can't know the numbers. iT's just a mental thing... ..............I don't know.. i give up !

hey, don't give up. I'll explain you how he did it:
While you follow his instruction, you choose the number 10a + b. Then you add the two numbers together, that's a + b. After that, subtract the new number from your original number, that's 10a+b - a+b = 9a. Now notice all multiple of 9: 90; 81; 72; ... ; 9; 0. They all have the same symbol. That's why he always guesses right

that's incredible ! I can't understan how it's possible?
