Answer 1

Ответ:

-82.75

Пошаговое объяснение:

1) -15.71 + 34.11 = 18.4

2) 18.4 - 24.48 = -6.08

3) -6.08 + 4.5 = -1.58

4) -1.58 - 81.17 = -82.75

Answer 2

To calculate the expression, simply follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction):

Given expression: -15.71 - (-34.11) - 24.48 - (-4.5) + (-81.17)

1. First, resolve the double negatives within parentheses: -15.71 + 34.11 - 24.48 + 4.5 - 81.17

2. Now, perform the addition and subtraction operations from left to right: (-15.71 + 34.11) - 24.48 + 4.5 - 81.17 18.4 - 24.48 + 4.5 - 81.17

3. Continue performing the addition and subtraction operations: -6.08 + 4.5 - 81.17

4. Finally, perform the last addition and subtraction: -6.08 - 76.67

The result is approximately -82.75.
