Question

−15,15−(−34,89)−(+24,43)−(−4,77)+(−81,88)

Answer 1

-15,15+34,89-24,43+4,77-81,88=-81,8

Answer 2

To perform the arithmetic calculation, we'll add and subtract the given values step by step:

1. Add the two positive numbers: +24.43
2. Subtract the negative number from the positive result: +24.43 - (-4.77) = +29.20
3. Add the two negative numbers: -15.15 + (-81.88) = -97.03
4. Finally, add the positive result and the negative result from the previous steps: +29.20 + (-97.03) = -67.83

The final result of the expression is -67.83.
