The answer is -1.


Multiplication or
Division (whichever comes first)
Addition or
Subtraction (whichever comes first)

Since there is a parentheses, do what is inside first.
In the parentheses, there is addition, subtraction and an exponent.
First do the exponent, and then add and subtract from left to right.
After you are done with your parentheses, you should have a #-1#.
Then multiply. Then add 1.
