FHE Lasagna Dinner

The night started out with a funny little telephone game. Then he gave a lesson on Agency. After that we all had lasagna and sat around and chatted with one another. It was great!

Brother Kennington's UNBELIEVABLE MATH PROBLEM

Here is a math trick so unbelievable that it will stump you.
Personally I would like to know who came up with this and
why that person is not running the country.  Let me know if it works for you.

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

Do you recognize the answer?
