Answer 1

-(8,31 +6,27) + (-8,44 +31,67) - 0,15=-14,58+23,23-0,15=8,5

Answer 2

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

1. Parentheses/Brackets
2. Exponents/Orders (i.e., powers and square roots, etc.)
3. Multiplication and Division (left-to-right)
4. Addition and Subtraction (left-to-right)

Let's break down the expression step by step:

B) -(8,31 + 6,27) + (-8,44 + 31,67) - 0,15

First, perform addition inside the parentheses:

1. -(8.31 + 6.27) + (-8.44 + 31.67) - 0.15

Next, calculate the sums within the parentheses:

2. -(14.58) + (23.23) - 0.15

Now, perform the subtraction operations:

3. -14.58 + 23.23 - 0.15

Finally, add and subtract from left to right:

4. (-14.58 + 23.23) - 0.15 (8.65) - 0.15 8.50

So, the result of the expression is 8.50.
