Answer :

[tex]-(-(-(-2)))=2[/tex]

-(-(-(-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  .
