Think of ANY NUMBER, then x2, then add 10, then divide it by 2, then subtract it by the original number.
I guarantee the answer will always be 5. |

@Touch;
4 - -1 is 5 you idiot.
4 - (-1) = 4 + 1 = 5 |

But it's because when you multiply a number by two, and divide by two later, you get the same damn number.
Adding 10 just makes it so it's always 5. Without that, you'd just get the same number you started with.
Not that great of a trick OP. |

Here is how the damn trick works idiots. Hey kisame, listen up you brat.
When I think of a number, let's say 50, I multiply by 2.
Now I have 100.
I add 10, but let's keep that separate for now.
So I have 100 + 10. Now I have to divide by 2.
So I have 100/2 + 10/2 which is 50 + 5.
Now I subtract the first number I started with, so that takes out the 50.
Voila, there is 5.
NOT TOO GOOD. |

x * 2 + 10/2 - x *2 and subtract the original number cancel each other out because 5 * 2 = 10 -5 = 5 if you substitute 5 for x Then you're left with 10/2 which is 5
Wow. |
