Help!!!!Does anyone know what 2 prime numbers subtracted together that equals 7? #3 20051214 08:26:09
Re: Help!!!!It's not possible, and here is a simple proof to show why: Last edited by Ricky (20051214 08:26:57) "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..." #4 20051214 09:25:07
Re: Help!!!!What about 2 and 5? Negatives are probably disallowed, huh? igloo myrtilles fourmis #5 20051214 10:19:56
Re: Help!!!!Yes i cant use negative numbers and 52 is 7 but if your trying to say 2+5 it would only equal3. #7 20051214 16:12:06
Re: Help!!!!Negative numbers are not primes, although one could certainly argue that they should be. But I'm not about to go and change the basic framework of math.
