Find two numbers from a single numberU have two numbers ..u must find a method to find a third number from this two numbers such that afterwards only the 3rd number is provided u should get back the first two number..One more thing to easy the work...the two numbers is in limit 0 to 255 .CAN ANY ONE????? eek #2 20060122 04:58:59
Re: Find two numbers from a single numberSounds like cryptography. I can't understand however, why the last number could be 256. That isn't in the extended ascii, nor could it be held by a character (in computers). "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #3 20060122 05:01:03
Re: Find two numbers from a single numberScratch that, summation of primes isn't 11. 11+5 = 16 and 13 + 3 = 16. How about summation of perfect squares?

Re: Find two numbers from a single numberMaybe I didn't explain it well. Have your function be the summation of perfect squares: "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #6 20060122 14:22:04
Re: Find two numbers from a single numberu think u dnt get what i mean.....we are given any two numbers between 0 and 256.From this two numbers we must obtain a 3rd number suc that afterwards we may be able to reproduce this two numbers from the single number..In wha u explained only i can be done to perfect square numbers...Guive a general one for all numbers #7 20060122 15:54:11
Re: Find two numbers from a single numberHow about this? I don't know if this is for a computer program or not, but I think that it can be adapted for any such situation. #8 20060122 16:11:14

Re: Find two numbers from a single numberIs there any method by doing some combination of different AND OR operations or any such operations on the two numbers and later then doing some other steps to obtain the two numbers from the single number?? #11 20060122 20:03:37
Re: Find two numbers from a single number
soorejmg, no function exists, has ever existed, or will ever exist.
Sorry irspow, it can't be. There are a few reasons. The first, is that there is a limitation. a, b and c can only be from [0, 255]. That's because a, b, and c can only be 8 bits each. A float (decimal value number) is 8 bits as well, but it can only store just as many numbers as an 8 bit integer can. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #12 20060122 20:14:35

Re: Find two numbers from a single number
HEy,,,u know something....i have been looking for some solution but i couldnt find one..So i asked u people....No one could... #14 20060123 02:24:01
Re: Find two numbers from a single numberNo soorejmg, that's not what I said. It will _NOT_ exist. There is _NO_ such function. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #16 20060123 03:09:01
Re: Find two numbers from a single numberThese are fairly in depth things. I will try to explain it the best I can, but I won't be surprised if you don't understand. These topics take quite a while to fully grasp. If you want to look up more information for yourself, this is known as Set Theory and more specifically, the Pigeon Hole Principle. If you have any questions, just ask. Last edited by Ricky (20060123 03:09:16) "In the real world, this would be a problem.

Re: Find two numbers from a single numberThanks irspow. That is certainly one of my options. I'm not quite sure what to do yet. At least I have a few years to decide.

Re: Find two numbers from a single numberHey Ricky,ur way of explanation is very nice.....realy...u can be a good teacher ..... Last edited by soorejmg (20060124 03:44:10) #20 20060124 04:36:18
Re: Find two numbers from a single numberYou are correct, f(x, y) is different than f(x) and f(y), but so is the explanation. "In the real world, this would be a problem.

Re: Find two numbers from a single numberrickyoswaldiow, that only works for 3. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #23 20060124 09:19:47
Re: Find two numbers from a single numberI am thinking about dice (because of another question on the forum): wouldn't it be the same as asking: "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #24 20060124 16:05:28
Re: Find two numbers from a single number
This one i understood.But not hat i asked.let A be the set above and B too.The connection between the domain and the range is through the function aplied on the domain set know?
