#-48#

Explanation:

First, let's make this easier on ourselves and simplify the problem before we do any multiplication. In the parentheses, we have #6--5--5#. Since subtracting a negative number is the same as adding the positive opposite (i.e. #6--5=6+5#), we can simplify the expression to get #(6+5+5)(-3)#.

Next, let's add up all of the numbers in the parentheses. #6+5+5=16#. This leaves us with #(-3)(16)#.

From here we just multiply the two numbers together to get our answer:

#-3*16=-48#
