Phone Number Trick

From the e-mail:

A calculator and your phone number: a mind-blowing combination.

--Note, if you are using a graphing calculator, do not enter all of the information at once. do each step one by one.--

1) Ignoring your area code, key-in the first 3 digits of your phone number into the calculator

2) multiply by 80

3) then plus 1

4) multiply by 250

5) plus the last four digit of phone number

6) plus the last four digit of phone number again

7) minus 250

8) divide by 2 at last

Now, it may because I'm still working whatever creeping crud sickness I've had the last couple of days out of my system, but this was entertaining for a good couple of minutes.
