Answer 3

To solve the expression, let's break it down step by step and perform the operations in the correct order, following the rules of arithmetic.

1. −15,42 − (−34,59): Subtracting a negative number is the same as adding its absolute value: $−15,42 + 34,59 = 19,17$

2. −24,72 − (−4,12): Again, subtracting a negative number is the same as adding its absolute value: $−24,72 + 4,12 = -20,60$

3. Adding the results from steps 1 and 2: $19,17 - 20,60 = -1,43$

4. Adding $−81,63$: $-1,43 + (−81,63) = -83,06$

So, the result of the given expression is $-83,06$.
