Explicación paso a paso:
1. - (3 - 2 - 1) + (- 5 + 7 + 4) =
- 3 + 2 + 1 - 5 + 7 + 4 =
6
----------------------------------------------
3. (- 4 + 7 + 2) + 9 - (- 3 + 4 - 3) =
- 4 + 7 + 2 + 9 + 3 - 4 + 3 =
16
----------------------------------------------
5. (- 8 - 3 - 9) + 4 + (- 2 + 9) =
- 8 - 3 - 9 + 4 - 2 + 9 =
-9
----------------------------------------------
7. - 2 - 4 + (- 8 + 4 - 6 + 7) =
- 2 - 4 - 8 + 4 - 6 + 7 =
-9
----------------------------------------------
9. (3 * 5 * 8 * 4) / (3 * 8) =
480 / 24 =
20
----------------------------------------------
11. {60 * (- 2)} / 10 =
{- 120} / 10 =
-12
----------------------------------------------
13. {60 / (- 5)} / {10 / (- 5)} =
{- 12} / {- 2} =
6
----------------------------------------------
15. - 60 / {10 / (-2)} =
60 / {- 5} =
