Answer 2

To solve this expression, 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 case, you only have addition and subtraction.

Let's break down the expression step by step:

1. Start with the parentheses: (-5) - (-7) = -5 + 7 = 2 (-3) (-7) = -3 * -7 = 21

2. Substitute the results back into the expression: 9 - 2 * 4 - 21

3. Perform the multiplications and divisions from left to right: 9 - 8 - 21

4. Perform the additions and subtractions from left to right: 1 - 21

5. Finally, perform the subtraction: 1 - 21 = -20

So, the value of the expression is -20.
