Step-by-step explanation:
1. 49 ÷ 7 + 6 × 4 - 8
7 + 6 × 4 - 8
7 + 24 - 8
31 - 8
= 23
2. 60 ÷ 3 + 15 × 2
20 + 15 × 2
20 + 30
= 50
3. 45 - (10 + 14) ÷ 3 × 2
45 - 24 ÷ 3 × 2
45 - 8 × 2
45 - 16
= 29
4. 36 + 42 ÷ (12 - 5) × 3
36 + 42 ÷ 7 × 3
36 + 6 × 3
36 + 18
= 54
5. (128 - 68) ÷ (35 + 25)
60 ÷ (35 + 25)
60 ÷ 60
= 1
6. 11 + 6 × 3 - 30 ÷ (16 - 6)
11 + 6 × 3 - 30 ÷ 10
11 + 18 - 30 ÷ 10
11 + 18 - 3
29 - 3
= 26
7. 46 ÷ (5 - 3) - 9 × 2
46 ÷ 2 - 9 × 2
23 - 9 × 2
23 - 18
= 5
8. 10 × 8 ÷ 5 - 3 + 9
80 ÷ 5 - 3 + 9
16 - 3 + 9
13 + 9
= 22
9. 56 ÷ 8 + 12 - 6 × 3
7 + 12 - 6 × 3
7 + 12 - 18
19 - 18
= 1
10. 55 × 4 + 18 ÷ 6 - (138 + 62)
55 × 4 + 18 ÷ 6 - 200
220 + 18 ÷ 6 - 200
200 + 3 - 200
203 - 200
= 3
11. 35 × 2 - 138 ÷ 2
70 - 138 ÷ 2
70 - 69
= 1
12. 70 + 65 ÷ 5 × 2
70 + 13 × 2
70 + 26
= 96
