Answer 2

Let's solve the expressions step by step:

1. 80 - 6 × 7 + 29: First, we perform the multiplication: 6 × 7 = 42. Then, we subtract: 80 - 42 = 38. Finally, we add: 38 + 29 = 67. So, the result is 67.

2. (84 - 28) ÷ (7 × 8): Inside the parentheses, we have a subtraction: 84 - 28 = 56. Then, we multiply: 7 × 8 = 56. Finally, we divide: 56 ÷ 56 = 1. Therefore, the result is 1.

3. 6 × (62 - 53) - 50: Inside the parentheses, we have a subtraction: 62 - 53 = 9. Then, we multiply: 6 × 9 = 54. Finally, we subtract: 54 - 50 = 4. Hence, the result is 4.

4. 38 + 42 ÷ 6 × 4: First, we perform the division: 42 ÷ 6 = 7. Then, we multiply: 7 × 4 = 28. Finally, we add: 38 + 28 = 66. Therefore, the result is 66.

To summarize:

1. 80 - 6 × 7 + 29 = 67
2. (84 - 28) ÷ (7 × 8) = 1
3. 6 × (62 - 53) - 50 = 4
4. 38 + 42 ÷ 6 × 4 = 66
