Title: hardest math problem-1
Post by: Mohammad Salek Parvez on January 16, 2017, 03:28:04 PM

After the solution of Fermat's Last Theorem , 3 math problems are ranked as the hardest. these are :
(1). Goldbach conjecture:
(2). P  vs  NP
(3). Riemann Hypothesis. 
Golbach Conjecture: every even number greater than 2 can be expressed as sum of two primes. It is  more than 250 years old. It has been neither proved nor disproved ( by means of a   counterexample) . Using super computers it has been verified up to  4000...... ( 18 zeroes)।  but this means nothing for a mathematician.

Yes, MR SKR,
# 3  has a lot of uses.
# uses of # 2  aren't still understood.
# 1 might be nothing more than a brainstorm. but if u can solve it, you will get worldwide recognition & lot of money as prize. it's like that Messi kicks & goals. He gets pleasure & millions of dollars. But this GOALING has no significance in your life.
