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

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

No. Some of the world's hardest maths problems have remained unsolved for centuries.
