Best answer

-3+2--2-(5/-2)(6)

 

You do the () parts first, but nothing can be simplified further.

-3+2--2-(5/-2)(6)

Next, do multiplications. Treat "--" as -1 times -1 = +1

The -2 in 5/-2 can be brought to the top (-5/2). You are multiplying the top and bottom by -1, so nothing changes. 

-3 + 2+2-(-5/2)(6)

-3 + 2+2+(5/2)(6)

-3 + 2 + 2 + 30/2

Next, do divisions (remember it using: Please Excuse My Dear Aunt Sally ) for the order of operations.

Please - Parentheses  
Excuse - Exponents
My - Multiplication
Dear - Division
Aunt - Addition
Sally - Subtraction

 

-3 + 2 + 2 + 15

Addition is next

-3 + 19

Finally, do subtractions

Answer: 16
