Răspuns:

Explicație pas cu pas:

1.

5 - 2 + 3 - 1 = 5

2.

2 - 5 + 8 - 2 = 3

3.

/5 - 8/ - /5 - 4/ - /9 - 1/ + /13 - 16/ = /-3/ - /1/ - /8/ + /-3/ = 3 - 1 - 8 + 3 = -3

4.

7 + /8 - 9/ - /27 - 25/ = 7 + /-1/ - /2/ = 7 + 1 - 2 = 6

5.

-8 - 12 + /-36 + 25/ - /-7 + 8/ = -20 + /-11/ - /1/ = -20 + 11 - 1 = -10

6.

8 - /4/ - /16 - 25/ + 6 = 8 - 4 -/-9/ + 6 = 8 - 4 - 9 + 6 = 14 - 13 = 1
