Here is a math trick so unbelieveable that it will stump you.

1. Grab a calculator.
2. Key in the first four digits of your home telephone number but not the area code.
3. Multiply by 80.
4. Add 1.
5. Multiply by 250.
6. Add the last four digits of your telephone number.
7. Add the last 4 digits of your telephone number, again.
8. Subtract 250.
9. Divide the number by 2.

Do you recognize the number? :lol: :thumbup:

Yes, you may have one extra digit in there.

Tell me what I'm doing wrong, do I press the equal sign after each step? My calculator gives me an error message!!
