You should learn the "order of operations".  That will help alot with these crazy problems.  Any time you are multiplying or dividing by "0", your answer is going to be 0....All the other stuff is mumbo-jumbo in this problem.

-2 + 12 - 2 x 2 x 2 divided by 2 x 0 x 3 (here's the key to the answer)

I can tell you the answer right now is  0

do the multiplication first ( 2 x 2 x 2  = 8) divided by 2 x 0 x 3 = 0

-2 + 12 = 10 - 8 divided by 0
2/0 = 0
