-(-(-(-2))) is not a question, so it has no answer.
But if you'd like to clean it up and make it look less ugly, then you should notice that there are 4 minus-signs operating on the '2'. Every two minus-signs cancel each other, so 4 of them definitely result in total annihilation of all the minus-signs, and the whole revolting expression is equal to just*** 2 *** .
− ( − ( − ( − 2 ))) = 2
-(-(-(-2))) simplifies through a series of negations. Each pair of negatives cancels out, so we ultimately end up with the answer of 2. The last operation, however, and the sign should be closely monitored; thus, the final answer is 2.
