Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses: Perform operations inside the parentheses first.
2. Exponents: Handle any exponents if present (none in this case).
3. Multiplication and Division: Perform any multiplication and division from left to right.
4. Addition and Subtraction: Perform any addition and subtraction from left to right.

Now, let's solve the expression step by step:

0.7 - (11.6 + 14.9) - (5.5 - 12.6)

Step 1: Parentheses 0.7 - 26.5 - (-7.1)

Step 2: Addition and Subtraction 0.7 - 26.5 + 7.1

Step 3: Addition and Subtraction -25.8 + 7.1

Step 4: Addition and Subtraction -18.7

So, the result of the expression is -18.7.
