nutternutin Posted March 24, 2004 Share Posted March 24, 2004 key in the first 3 digits of your phone number. Multiply by 80 Add 1 Multiply by 250 Add the last 4 digits of your phone number Add the last 4 digits of your phone number again. Subtract 250 Divide number by 2 Do you recognize the answer?

MrA Posted March 24, 2004 Share Posted March 24, 2004 Ok, I'll be one who says this has been posted already. Please don't flame me, but I thought I'll get it over with since someone's gonna say it anyways. I don't mean to be rude. This has been posted already! Now that that's over, it works for any 7 digit number. Just write down the math, simplify and you'll see why. Link to comment Share on other sites More sharing options...

Cody Posted March 24, 2004 Share Posted March 24, 2004 if you see at the top you are multiplying 81*25 which is 20250 later you subtract 250 and divide by two which makes it 10000 if you multiply that by the first 3 digits you will get the first part and you have to add the last 4 twice since you are dividing by two Link to comment Share on other sites More sharing options...
