Solution:
1. Evaluate the individual components inside the brackets:
- First bracket: (-8+6)-(-3-2)
* Evaluate inside the inner part: -8+6 = -2 and -3-2 = -5
* Continue with the outer operations: (-2) - (-5) = -2 + 5 = 3
- Second bracket: (4 - (2-1))
* Evaluate inside the inner part: 2-1 = 1
* Continue with the outer operations: 4 - 1 = 3
2. Add the results of each bracket:
3 + 3 = 6
