Answer 2

To help you with this expression, I assume you meant to write it as:

((-9 + 7,1) * (-1 + 4/9))

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

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (left to right)
4. Addition and Subtraction (left to right)

Let's proceed with the calculation:

Step 1: Parentheses/Brackets ((-9 + 7,1) * (-1 + 4/9))

Step 2: Addition inside the parentheses ((-1,9) * (-0,1111))

Step 3: Multiplication -1,9 * -0,1111

To multiply two negative numbers, we get a positive result:

Step 4: Calculate the result 1,9 * 0,1111 ≈ 0,21009

So, the result of the expression is approximately 0,21009.
