Proving the Riemann conjecture.
That's a easy one chickens
Different people find different things hard. So a problem that is hard for someone may seem easy to you and one that you think is hard may be easy for someone else. It is, therefore, not possible to answer the question.
There is no "hardest" problem. Something that you might find hard might appear easy to someone else and conversely. Also, some of the harder problems do not have solutions yet - if they had been solved then they could not have been so hard!

Anyone can if they work hard at it.
I assume you mean "whole world" rather than "hole world". There is no "hardest math question" because one's field of knowledge may be different to another. Therefore, the hardest question for one person may be an easy one for others.

That's hard to say.
Oh, dude, the hardest math problem for a 6th grader? Well, I guess it would be one they can't solve, right? Like, maybe some crazy algebraic equation or a mind-bending geometry problem. But hey, who needs math when you've got calculators, am I right?

It really depends on who you're asking....
No. Some of the world's hardest maths problems have remained unsolved for centuries.
