Answer 2

Let's break down the expression step by step:

1. Start by simplifying the expressions within the parentheses:

   11.7 + 14.8 = 26.5 3.5 - 12.5 = -9

2. Now, you have the expression as:

   17.8 - 26.5 - (-9)

3. To remove the double negative, change the subtraction of a negative to addition:

   17.8 - 26.5 + 9
