ProMagma  Nov 7, 2017

ProMagma  Nov 7, 2017

HAHAHA!!!!!...I know it will come to 29997  !!!

I think I have the trick....although I'm not sure

You ask the person to pick a 4 digit number

Then...you add  9999 * 2   =  19998  to that number

This will be the "future number"

When they pick the next number.....you make sure that the number you pick and  their second number sum to 9999

When they pick their final number......you do the same thing......you make sure that your final number and their final number sum to 9999

So....the future number is just   their first number +  9999 * 2

Am I close ???

CPhill  Nov 7, 2017

Yes, You were ​very close, spot on infact!!!

I learned this in 3rd grade and it took me a week to figure it out!

ProMagma  Nov 7, 2017

One question.....you must be able to use numbers that have 3 leading 0s as possible four digit numbers????

Because....had I picked 9999 originally and then 9998....you would have had to use 0001 to get the first sum of 9999

And if I had picked 9997 as my last number.....you would have had to use 0002   to get the second 9999 sum......

Is this correct ???

CPhill  Nov 7, 2017

Yes, those would have been the nubers that I would have picked

You got it!!

ProMagma  Nov 7, 2017

I actually think the factor is that ProMagma was allowed to choose a number to add to the pile.  If he didn't get to choose, I really don't know how one would get this trick to work.  Unless mindreading over computers was developed.

This isn't really a trick right? It is just some subtraction and addition.......

It's like those pick a random number......now subtract you original number.

It just cancels out...
