Answer 4

12−2^3+4÷2+2^4

Answer 5

To simplify the expression using the order of operations, we follow these steps:

1. Evaluate exponentiation:

12 - 2^3 + 4 ÷ 2 + 2^4
= 12 - 8 + 4 ÷ 2 + 16
= 12 - 8 + 2 + 16

2. Perform multiplication and division from left to right:

12 - 8 + 2 + 16
= 4 + 2 + 16
= 6 + 16
= 22

Therefore, the simplified expression is 22.

Answer 9

To simplify the expression using PEMDAS, we follow these steps:

1. Perform multiplication and division from left to right:

72 ÷ 12 + 26 − 8 ⋅ 3
= 6 + 26 − 8 ⋅ 3

2. Perform addition and subtraction from left to right:

6 + 26 − 8 ⋅ 3
= 32 − 8 ⋅ 3

3. Perform the remaining multiplication:

32 − 8 ⋅ 3
= 32 − 24

4. Perform the subtraction:

32 − 24
= 8

Therefore, the simplified expression is 8.

Answer 11

To simplify the expression using the order of operations, we follow these steps:

1. Perform the division:

63 + 4 ÷ 2 + 44
= 63 + 2 + 44

2. Perform addition from left to right:

63 + 2 + 44
= 65 + 44

3. Perform the final addition:

65 + 44
= 109

Therefore, the simplified expression is 109.
