5 - (49 ÷ 1 - 5) × 2 + 9 - 3
5 - 44 x 2 + 9 - 3
5 - 88 + 9 - 3
-83 + 9 - 3
-74 - 3
= -77

6)

(2 + 76 ÷ 1 + 9) + 4 - 3 × 9
(2 + 76 + 9) + 4 - 3 × 9
87 + 4 - 3 × 9
87 + 4 - 27
91 - 27
= 64

7)

5 × 5 - 7 + 82 ÷ (2 × 1) + 5
5 × 5 - 7 + 82 ÷ 2 + 5
25 - 7 + 82 ÷ 2 + 5
25 - 7 + 41 + 5
18 + 41 + 5
59 + 5
= 64

8)

7 × 7 + 1 + 16 ÷ 8 - (6 - 7)
7 × 7 + 1 + 16 ÷ 8 - 6 + 7
49 + 1 + 16 ÷ 8 - 6 + 7
49 + 1 + 2 - 6 + 7
50 + 2 - 6 + 7
52 - 6 + 7
46 + 7
