1 The world once regarded 10 mathematical problems that no one could solve as the world's 10 major mathematical problems, and promised that whoever could solve any one of them would be awarded 1 10,000 dollars!
As far as I know, three roads have been conquered.
At present, most scholars in the world think that the most difficult mathematical problem is Goldbach conjecture, which appeared in18th century. At present, the closest solution in the world is "1+2" by China mathematician Chen Jingrun, which is only one step away from the final "1+ 1".
Special statement: 1+2, 1+ 1 is by no means the proof of 1+ 1=2 said by those fools.
