Пошаговое объяснение:

6 – (– (–7) + (–3)) – (– (– 5) – 1 – (–8))

=6-7+3-5+1-8=-10

Answer 2

To solve the given expression, let's break it down step by step:

1. Start with the innermost parentheses: (–7) and (–3).

   • The sum of -7 and -3 is -10.

2. Replace the innermost parentheses with the calculated result: (– (-10)).

3. Simplify the expression inside the updated parentheses:

   • The negative of -10 is 10.

4. Replace the updated parentheses with the calculated result: (10).

5. Next, consider the expression in the second set of parentheses: (– (-5) – 1 – (–8)).

   • The negative of -5 is 5.
   • Subtract 1 from 5: 5 - 1 = 4.
   • The negative of -8 is 8.

6. Replace the second set of parentheses with the calculated result: (5 – 4 – 8).

7. Simplify the expression inside the updated parentheses:

   • Subtract 4 from 5: 5 - 4 = 1.
   • Subtract 8 from 1: 1 - 8 = -7.

8. Replace the updated parentheses with the calculated result: (-7).

9. Now, substitute the values back into the original expression: 6 – (-10) – (-7).

10. Negate the values inside the parentheses:

    • The negative of -10 is 10.
    • The negative of -7 is 7.

11. Simplify the expression:

    • 6 - 10 + 7 = -4.

Therefore, the value of the expression 6 – (– (–7) + (–3)) – (– (–5) – 1 – (–8)) is -4.
