1) Have somebody pick a number (any number will work, but it is much easier for them to do the math if they pick a smaller number). They need to remember this number.
2) Double the number
3) Now tell them you want them to add a number that you choose to the new number they got from Step 2. You may choose any number you want. (At the end of the trick, when you Read their Mind", the answer that they will ultimately have will be half of this number you told them to add.
4) Divide the number by 2
5) Subtract the number they started with.
Tell them to think hard about the number they currently have, and send a telepathic message to you. Put your fingers on the sides of your head (temples)  to show that you are concentrating hard... then  reveal the number they are thinking of (half of what you told them to add!).
How It Works
When they start with a number, and then subtract the number they started with  they cancel each other out. When they double a number, and then divide it by 2, they are cancelling each other. So the only that doesn't get cancelled is that tell them to add a number, and then the next step is to divide by 2  so they number you told them to add will be cut in half.

1.Get a calculator.(you won’t be able to do this one in your head)
2. Key in the first three digits of your phone number (Not the area code)
3. Multiply by 80
4. Add 1
5. Multiply by 250
6. Add the 4 digits of your phone number
7. Add the last 4 digits of your phone number again.
8. Subtract 250
9. Divide number by 2
Do you recognize the answer?
Here's an example:
Let's say your phone number is 5946284.
Multiply by 80
594 x 80 = 47,520
Add 1
47,250 + 1 = 47,251
Multiply by 250
47,251 x 250 = 11,880,250
Add the last 4 digits of your phone number
11,880,250 + 6284 = 11,886,534
Add the last 4 digits of your phone number again
11,886,534 + 6284 = 11,892,818
Subtract 250
11,892,568  250 = 11,892,568
Divide number by 2
11,892,568 / 2 = 5,946,284
That's the phone number we started with!

Pick a number between 1 and 10. Then multiply by 9. Now you should have a two digit number. Now add those two digits. Whatever number you have subtract it by 5. And you should have 4. Did you get it right?
