Answer 3

Let's solve each of the given arithmetic expressions step by step:

1. 6 + (-11) + 7 + (-8): Start by adding the positive numbers together: 6 + 7 = 13. Now, let's add the negative numbers: -11 + (-8) = -19. Finally, add the positive sum to the negative sum: 13 + (-19) = -6.

   Therefore, 6 + (-11) + 7 + (-8) = -6.

2. 11 + (-5) + 6 + 1 + (-4): Combine the positive numbers: 11 + 6 + 1 = 18. Combine the negative numbers: -5 + (-4) = -9. Add the positive sum to the negative sum: 18 + (-9) = 9.

   Therefore, 11 + (-5) + 6 + 1 + (-4) = 9.

3. -10 + 2 + (-5) + (-8) + 12: Combine the positive numbers: 2 + 12 = 14. Combine the negative numbers: -10 + (-5) + (-8) = -23. Add the positive sum to the negative sum: 14 + (-23) = -9.

   Therefore, -10 + 2 + (-5) + (-8) + 12 = -9.

4. -40 + 5(-25) + (-35) + 10: Multiply 5 by -25: 5(-25) = -125. Combine the positive numbers: -40 + 10 = -30. Combine the negative numbers: -125 + (-35) = -160. Add the positive sum to the negative sum: -30 + (-160) = -190.

   Therefore, -40 + 5(-25) + (-35) + 10 = -190.

I have provided the solutions for each of the given arithmetic expressions.
