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.
Ricky was correct in that there are no solutions to your problem.
Yes i cant use negative numbers and -5-2 is -7 but if your trying to say -2+5 it would only equal3.
What about 2 and -5? Negatives are probably disallowed, huh?
It's not possible, and here is a simple proof to show why:
Anyone plz help me!!!!
Does anyone know what 2 prime numbers subtracted together that equals 7?
