Phone Number Magic Trick 1. Grab 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 last 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 crazy huh???

lol very nice, i know mch of those, but this one was still unknown to me. now i've got something to do again when im with some friends on a rainy boring day.... well at least for about 20 seconds.

whats it supposed to do? im in uk & usin 1st 3 numbers and last 4 and ended up with the 1st 3 numbers and last 4

What is supposed to happen? The last four digits in my phone number start with a 0 so thats probably what screwed it up.

Useless but very funny, head cracking on Christmas Day, I'll let my friends calculate that out of their heads with a paper and a pen .. ^^;

That's pretty cool. All it shows, at the end of the "math" is your phone number not including your area code.
