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.

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?

So what was this supposed to show?  The number was meaningless for me.

Hmmm. it is supposed to result in your telephone number.

It comes out to be your full telephone number...amazing. Try it again, Walt,
and see if your own phone number doesn't show up as the answer.

Wow!!!  Very cool!

Walt, the number I got after going through all the calculations, was my
full phone number.

I must be using the wrong kind of calculator. This doesn't seem to work well
with a 10-key. Or, maybe it's just me.lol

I tried it again, and it worked perfectly.  I guess I didn't read, "not the
area code" the first time!

Well, folks, I hate to ruin this for you all, but I am a Math Professor, so
I couldn't resist analyzing all of this.
It might look amazing, but it's actually an interesting algebraic problem.

OK-- here's the math solution. First, you have to realize that the value of
a number, say 587, is 5*100 + 8*10 +7.

Likewise, the value of say 9876 is 9*1000 + 8* 100 + 7*10 +6

So, if your telephone number is: "abcdefg", the value is:

1000000a + 100000b +10000c + 1000d + 100e + 10f + g

So, here's the solution:

Key in the first three digits of your phone number (NOT the area
code)

"abc"=

100a + 10b +c

Multiply by 80

80(100a + 10b +c)

add 1

80(100a + 10b +c)+1

Multiply by 250

250 * [80*(100a + 10b + c) +1]

Add the last 4 digits of your phone number

So we add: "defg" which means:

250 * [80*(100a + 10b + c) +1] + 1000d + 100e + 10f +g

Add the last 4 digits of your phone number again:

250 * [80*(100a + 10b + c) +1] + 1000d + 100e + 10f +g +1000d + 100e + 10f
+g

Subtract 250

250 * [80*(100a + 10b + c) +1] + 1000d + 100e + 10f +g +1000d + 100e + 10f
+g - 250

Before we do the last step of dividing by 2, let's simplify. Remember that
old distributive rule. That's what we do with the first part, noting that
80*250=20000

2000000a + 200000b + 20000c + 250 +1000d + 100e + 10f + g + 1000d +100e +
10f + g -250

Note that the "250" cancels, and combining like terms we get:

2000000a + 200000b + 20000c +2000d + 200e +20f + 2g

Finally, dividing by 2 we get our desired telephone number:

1000000a + 100000b + 10000c + 1000d + 100e + 10f + g

That's it.

Thanks Mel,  I wasn't up to typing an explanation!  And who says you need  a
calculator when a pen and a bit of paper suffices?

Thanks, Mel. I loved Math when I was a student, especially
algebra. I just wish my teacher had been as good as you are.
