Awesome Math Trick!

1. Ask a friend to pick any number
2. Tell them to add 5
3. Multiply by 2
4. Subtract 4
5. Divide by 2
6. Subtract their original number

No matter what number they pick, the answer will always be 3!

For example:

I pick 7

7 + 5 = 12
12 x 2 = 24
24 - 4 = 20
20/2 = 10
10 - 7 = 3

Pretty cool, huh?
