what is the worlds hardest math problem?

Just as there's no largest number, there is no hardest math problem. Go to http://www.claymath.org/ for some hard problems.

If you can solve one of these, you'll get $1 million dollars.

The proving of Fermat's Last Theorem is also a good example of a difficult math problem. It went unproven for over 350 years, untill Andrew Wiles found a proof back in 1995.

1+1

1+1

the fact that 2+2=5 in large quantities of 2

-95 - 864 + .9845 x 164 3/4 + -587 = ?

There are many. How about, provide me with a procedure for factoring any number in nlogn time.

It would probably finding the ending to pi, it has not yet been solved and i think it is 22/7

i read a book titled something like that once, the answer is 1+1

I think it boils down to the "singularity" of black holes.
