Answer 3

1. (24:6 + 5 × 7) - (45:5 + 7 × 4) + 10

Order of operations:

1. Perform multiplication: 5 × 7 = 35
2. Perform division: 24:6 = 4, 45:5 = 9
3. Perform addition: 4 + 35 = 39, 9 + 28 = 37
4. Perform subtraction: 39 - 37 = 2
5. Perform addition: 2 + 10 = 12

Therefore, the order of execution for the expression is: 2, 3, 1, 4, 5.

2. (36:6 + 5 × 9) - (40:5 + 7 × 3) + 10

Order of operations:

1. Perform multiplication: 5 × 9 = 45, 7 × 3 = 21
2. Perform division: 36:6 = 6, 40:5 = 8
3. Perform addition: 6 + 45 = 51, 8 + 21 = 29
4. Perform subtraction: 51 - 29 = 22
5. Perform addition: 22 + 10 = 32

Therefore, the order of execution for the expression is: 1, 2, 3, 4, 5.
