Ответ:

12+(-20)-(-11)-(-6)-10=12-20+11+6-10= -1.

Answer 2

Let's simplify the expression step by step:

1. Start with the addition and subtraction of numbers within parentheses: 12 + (-20) - (-11) - (-6) - 10

2. Remove the double negatives: 12 + (-20) + 11 + 6 - 10

3. Continue with the addition and subtraction: (-20 + 11 + 6) + (12 - 10)

4. Simplify within each set of parentheses: (-3) + (2)

5. Finally, perform the remaining addition: -3 + 2 = -1

So, the final result of the expression is -1.
