Q
What is the most difficult mathematical problem ever?
A
Expert Answer
The Riemann Hypothesis (about distribution of prime numbers) has remained unsolved for over 160 years and is one of the seven Millennium Prize Problems ($1 million reward). Other candidates: P vs NP, Navier-Stokes existence, and the Collatz conjecture. Their difficulty lies in requiring entirely new mathematical approaches.
