Amazing Math Proglem
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?

Actually this is rather simple hun. i know you don't see things well in math but I'm going to explain this as best I can. To get your phone number to translate into a 7 digit number you basically only need to multiply your area code by 10000 and then add the last 4 digits of your phone number. If we write this equation down into its algebraic form and then break it up into parts we can see how this was accomplished.
Assume X= your area code and Y= your last 4 digits
Your equation was stated thusly:
{ [(80X+1) x250] + 2Y - 250} /2 or in verbal: 80X plus 1 multiplied by 250 plus 2Y -250 summation divided by 2
So we multiply 80x by 250. 1 by 250. Add 2Y. Subtract 250. Sum it up and divide by 2
Our second step of the algebraic looks like this:
[20000X + 250 + 2Y - 250] / 2
If we look in the parenthesis we see we have a +250 and a -250 which cancel each other
Now we have:
[20000X + 2Y] / 2
we can now look at it as 2 parts.
20000x / 2 + 2y / 2
this is pretty straight forward. since the entire thing was divided by 2 and we see that 20000x can be divided by 2 and 2Y can be divided by 2 we now have:
10000X + Y
If we look at our values for X and Y and plug them in it becomes increasingly clear we met the intitial criteria. our area code has been multipled by 10000 and we added our 4 digit number to it. My phone number will be used as an example. It is 693-4129
Plug the 693 in for x getting:
10000 x 693 = 6930000
Now we plug in Y:
6930000 + 4129= 6934129
looks like my phone number huh?
Welcome to Algebra II folks. Most of you should have had it no later then 11th grade. If you did not see it coming, shame on you for not paying attention in school.
An thats the math lesson for the day.
And as to why someone that came up with this not running the world?? I submit that the ones running the world are on about an 11th grade level of thinking so basically they are.
