Neat Trick?

Question

Here is a neat math trick, that may 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??




Star if you like it

It will only work on 7 digit phone #'s

Answer 1

very neat trick ... very imaginative ... took me some minutes to figure how it works ...

1. multiply 80 by 250 = 20000
2. any number multiplied by 20000 immediately doubles the number (the four zeroes are reserved for the last 4 digits)
3. you add the last four digits twice, meaning you also doubled the number.
4. dividing a doubled number by 2, takes you to the original number.
5. the adding of 1 before multiplying by 250 and subtracting 250, which cancels out, is a neat diversionary trick.

kudos to your mathematical mind ....

nice line to ask the number of someone you're attracted to ....

Answer 2

It is really amazing...even though I knew this math trick already. Here is another math trick for you:


Why did the Disney Imagineers choose 1939 as the base year for when lightning would strike The Hollywood Tower Hotel?

I thought about that recently, and for this "experiment", I'm using the Florida Tower as a base "object" [because it opened in 1994].


This experiment hints to use the year 1939 to find out what year Tower would be celebrating its 13th birthday.

First, one would take a calculator, and subtract 19 from 39. The answer is 20. Subtract the all-important number from Tower, 13, from 20. You get 7.

The first answer you got was 20, and if you suffix the second answer, 7, you get "207", possibly a reference to "2007" when Tower would turn 13 (which it actually did in July 2007).

Try it yourself...it's kinda creepy when you realize that this little trick actually works. I don't think it's a coincidence.

Answer 3

Wow that's so cool! I tried it and didn't work at first because of my UK no. But then I tried it with the last 7 digits of my no. and it worked - it's a good trick!! :)

Answer 4

Interesting, It worked

Answer 5

i learned that at the outdoor lab. what u can also do is get a hard white lifesaver and while u've got the night vision thing going look in the mirror and crack the lifesaver and u can see a light. so awsome

Answer 6

didn't work for me on mobile or land line but I'm in UK so may not work on our numbers but gonna star ya any way

Answer 7

wow its amazing i ave 2 show my frenz

Answer 8

haha woww
what in the worlddd

Answer 9

star omg so cool

Answer 10

That's pretty cool, but weird...
