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


>Grab a calculator. (you won't be able to do this one in your Head)
>1. Key in the first three digits of your phone number (NOT the Area code)
>2. Multiply by 80
>3. Add 1
>4. Multiply by 250
>5. Add the last 4 digits of your phone number
>6. Add the last 4 digits of your phone number again.
>7. Subtract 250
>8. Divide number by 2
>
>Do you recognize the answer ??

Here's another trick: Multiply the first 3 digits of your phone number by 10,000. Add the last 4 digits of your phone number. Whoa....

but... umm... you have to know the both the prefix and the last 4 to work(steps 5 and 6) and the answer ouputs the prefix and the last 4... so...

I swear I posted the explanation somewhere. Well, here it is again. It's just simple high school algebra:

Let A = first 3 digits of your phone number
Let B = last 4 digits of your phone number

Write out the whole equation and include quotes to help separate the formula:

(((A X 80) + 1) X 250 + B + B - 250) / 2

Multiply out:

((A X 80) X 250 + (1 X 250) + (2 X B) - 250) / 2

then

((A X 80 X 250) + 250 + (2 X B) - 250) / 2

then

((20,000 X A) + (2 X B)) / 2

divide out:

(10,000 X A) + B

therefore, the "trick" works with any 7 digit number

then

((20,000 X A) + (2 X B)) / 2

divide out:

(10,000 X A) + B

therefore, the "trick" works with any 7 digit number

Nah, he's just single... hence he's available for all your math calkulashunz on a FRIDAY NIGHT

[Skylinegtr06]

omg what is this? This is just a long way to see your own phone number. How is it amazing when you still have to input all seven numbers.
