Answer 1

=12+(8,5-32,5)+19-15=12-24+19-15=-12+19-15=-8

Answer 2

Let's solve the expression step by step:

1. First, perform the operation inside the parentheses: 17 - 65 = -48

2. Next, perform the multiplication: 0.5 * (-48) = -24

3. Then, perform the division: 38 / 2 = 19

4. Now, add up the results: 12 + (-24) + 19 - 15

5. Finally, combine the numbers: 12 - 24 + 19 - 15

6. Now, perform the addition and subtraction from left to right: -12 + 19 - 15

7. Continue the calculations: 7 - 15

8. And finally: -8

So, the result of the expression is -8.
