I know your phone number

[bowwow]

This is an unbelievable MATH problem. A must with a calculator.

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.
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??

try add = plus

Interesting, its simple Math though;

1. Key in the first three digits of your phone number --> (Lets say this is 'a')
2. Multiply by 80 --> (80a)
3. Add 1 --> (80a+1)
4. Multiply by 250 --> {(80a+1)x250}
5. Add the last 4 digits of your phone number --> (Lets say this is 'b') --> {(80a+1)x250} + b
6. Add the last 4 digits of your phone number again. (Add 'b' again) --> {(80a+1)x250} + b + b --> {(80a+1)x250} + 2b
7. Subtract 250 --> {(80a+1)x250} + b + b --> {(80a+1)x250} + 2b - 250
8. Divide number by 2 --> {(80a+1)x250} + b + b --> [{(80a+1)x250} + 2b - 250] / 2 = c ('c' is your phone number without the area code)

Simplifying this, we get;

125(80a) + b = c

Now 'c' can also be rewritten as [10000a + b] (Try it with your phone number, say its 7865432 = 10000(786)+ 5432)

so 125(80a) + b = 10000a + b

So Left Hand Side = Right Hand Side --> Logic

I know, I have way too much time on my hands

Looks like somebody is a Math Nerd

you still need the last 4 digits to do it

worked for me, but it added an extra number
