I have a little number trick to play on ya! See if you can figure it out!?

Question

Pick any number from one to one hundred







Multiply than number by two






Add the number eight to what you have now.






Divide this total by two







Subtract your original number from what you have now.







Let me use my mental telepathy (Ha-Ha)


You now have the number four, after subtracting the number you started with. You have 4
Four, didn't ya? Did you like that? Tell me what you think!

A couple of you said its SO easy, and it is, but tell me how it works. Prove to me your intelligence (and it is really easy to explain!) If no one does in a few days, I'll tell you how!

Exactly! CBL123, you're getting the 10 points!

Answer 1

It doesn't matter what number a person chooses......
It matters what number you tell them to add to it....
the answer will always be half of the number you told them to add.

It all has to do with "canceling" out numbers.....you said multiply....then add the special number....then divide (that cancels out the multiplication, and divides your special number in half) and then you subtract the remainder from the original number....leaving you with half of your special number!!! :)

Someone in my family showed me that trick a while back! I love it! Some people really can't figure it out for a while...they will ask you to do it over and over again till they finally catch on.

Answer 2

That was a pretty simple algebra trick. I've done harder ones in 4th grade, but it's decent, and most people wouldn't understand how you did it.

Answer 3

Whoa cool. But thats just something that has to deal with math really. I learned it in class.

Answer 4

Great trick! Thanx for the fun ;)

Answer 5

Ehh... It's simple.

Answer 6

you must be some kind of a mathematical genuis or something

Answer 7

bleh. i've heard of this years ago. nuthin new.
