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).

Let's break down the expression step by step:

1. Inside the innermost parentheses:

   • 8 + 31 = 39
   • 271 + 68 = 339
   • 74 + 31 = 105

2. Replace the expression with the calculated values: -(39 + 339 + 105) - 0.15

3. Add the numbers inside the outer parentheses:

   • (39 + 339 + 105) = 483

4. Replace the expression with the calculated value:

   • 483 - 0.15

5. Finally, subtract 0.15 from 483: 483 - 0.15 = 482.85

So, the result of the expression is 482.85.
