Answer 2

To solve this mathematical expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this expression, you have division, multiplication, and addition. Let's break it down step by step:

1. Start with the innermost parentheses: 8.68 / (-1.4) = -6.2

2. Now, we can simplify the expression without parentheses: (-6.2 - 0.8) / 0.35 + 12.6

3. Continue with the addition and subtraction from left to right: -6.2 - 0.8 = -7.0

4. Now, the expression becomes: -7.0 / 0.35 + 12.6

5. Perform the division: -7.0 / 0.35 = -20.0

6. Finally, add 12.6: -20.0 + 12.6 = -7.4

So, the final result is -7.4.
