famous ones include the classification of finite simple groups, the poincare conjecture, fermat's last theorem
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!
The hardest question is too difficult to conjure.
"Difference" means subtraction. for example the "difference" between 9 and 2 is 7.
That is based on opinion.
Proving the Riemann conjecture.

no it is not hard

All you need to do is math, math, math! Also, in level one, go diagonal!
