Answer 1

Răspuns:

5 + 5 : 5 - 5 - 5 : 5 = 0

5 + 1 - 5 - 1 =

6 - 5 -1 =

1 - 1 = 0

7 × 7 - 7 : 7 + 7 : 7 = 49

49 - 1 + 1 =

48 + 1 = 49

6 × 6 : 6 : 6 + 6 : 6 = 2

36 : 6 : 6 + 6 : 6 =

6 : 6 + 6 : 6 =

1 + 1 = 2

3 + 3 + 3 : 3 + 3 : 3 = 8

3 + 3 + 1 + 1 =

6 + 1 + 1 =

7 + 1 = 8

4 : 4 + 4 - 4 : 4 × 4 = 1

1 + 4 - 1 × 4 =

1 + 4 - 4 =

5 - 4 = 1

8 - 8 : 8 - 8 : 8 + 8 = 14

8 - 1 - 1 + 8 =

7 - 1 + 8 =

6 + 8 = 14

9 × 9 : 9 - 9 : 9 × 9 = 0

81 : 9 - 1 × 9 =

9 - 9 = 0

2 + 2 × 2 + 2 : 2 - 2 = 5

2 + 4 + 1 - 2 =

6 + 1 - 2 =

7 - 2 = 5
