# Magic Gopher

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.

oh，my god！he is right

So scary~

C'était trop amusant

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?

not correct!!

you did wrong not him

Can i know how he does it ??
