If you add the last 4 digits twice and then divide by 2 that is going to give you the original 4 digits at the end.

Basically multiply something by 80 and then by 250. well 80 multiplied by 250 = 20000 then divide that by 2 and you get 10000

so basically you are actually multiplying the first 3 digits by 10000

The full equation can be read like this.

Take the first 3 digits (eg 123)

multiply by 10000 (= 246000)

Then add the last four digits Eg(4567)

Then add them again (4567)

= a total of 2469134

thus when you divide by 2, you get 1234567 (your original number )

that above was meant to say multiply by 20000 (not 10000)

Still fun to have people do and look at their face when their phone number pops up.

Think of a number between 1 and 9

multiply it be 9

andd the 2 digits together until you get a single digit.

Give that digit a letter of the alphabet,

if it is 1=A, 2=B etc etc

Then think of a country that starts with that letter,

then think of an animal that starts with the last letter of the country,

then think of a colour that starts with the last letter of the animal.

But remember there are no Orange Kangaroos in Denmark

(that will make sense, hopefully, if you do the above)

That would work, but by addind the two numbers together you get 9...which is an I...

Yeah, Kelly, you're right. I alwasy end up with the green dog in Iceland...

Vettage, your formula works in Atlanta, GA, but now my brain hurts really bad!

Funny, I get an indigo quaggi in Indonesia. Lucky I did the endangered animals WP.

Whoops! I meant an indigo quaggi in Iraq.

in the original question you were meant to take 5 away from the number

so 9- 5 would be 4

which would give you D

ie denmark

kangaroo

orange

it might have helped had i not messed up.

OK, get out your calculators,....

1. Type in the first 3 digits of your 7 digit telephone number. (If you live where a telephone number has more or less than 7 digits,...pick any 7 digit number.)

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 by 2,....and the answer is,....YOUR TELEPHONE NUMBER!! (Or 7 digit number you picked).

Ok, math whizzes, can someone step up to the plate and tell me how that works? I've tried it with several numbers and it always comes out right!!

Consider my mind boggled,(just how I like it),
