My Grandpa forwarded me a neat math trick which you should try:

- Grab a calculator.
- Key in the first three digits of your phone number (NOT the area code)
- 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

The amazing result: Your entire phone number. This is a neat trick. But, being the ubergeek that I am, I had to figure out how it works.

**First Step:** Write out the instructions as a math equation. Let the first three digits of the phone number be ‘X’ and the last 4 digits be ‘Y’. The expected result will be 10000X + Y (your entire phone number).

[250(80X + 1) + 2Y - 250] / 2 = 10000X + Y

**Next Step:** Reduce the equation.

[20000X + 250 + 2Y - 250] / 2 = 10000X + Y

[20000X + 2Y] / 2 = 10000X + Y

10000X + Y = 10000X + Y

**Final Step:** It checks out, both sides are equivalent. Isn’t math fun!

Well, it’s official. You’re even dorkier than I could have ever imagined ðŸ™‚
