Answer 1

$\tt\displaystyle -15,23-(-34,66)-24,61-(-4,53)+(-81,67)=\\=-15,23+34,66-24,61+4,53-81,67=\\=19,43-24,61+4,53-81,67=\\=-5,18+4,53-81,67=\\=-0,65-81,67=\\=\bold{-82,32}$

Answer 2

To simplify the given expression, let's perform the operations step by step:

Step 1: −15,23−(−34,66) To subtract a negative number, we change the sign of the second number and then add it to the first number:

−15,23 + 34,66 = 19,43

Step 2: 19,43−24,61 Subtract 24,61 from 19,43:

19,43 - 24,61 = -5,18

Step 3: −5,18−(−4,53) Again, to subtract a negative number, we change the sign of the second number and then add it to the first number:

-5,18 + 4,53 = -0,65

Step 4: -0,65 + (-81,67) Add -81,67 to -0,65:

-0,65 - 81,67 = -82,32

So, the final result of the expression is -82.32.
