-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
