The given expression is a combination of addition and multiplication. First, we perform the addition inside the parentheses, which results in 7. Then, we multiply 7 by 32, which gives us the answer of 224. However, the given answer is 63, which is incorrect. Therefore, the correct answer for this question is not 63.

In the given expression, 4 is multiplied by 10 first, resulting in 40. Then, 102 is subtracted by 40, giving the final answer of 60.

The given expression follows the order of operations, which states that multiplication should be done before addition. So, first, we need to calculate 4 x 2, which equals 8. Then, we add the result to the sum of 2 + 52, which equals 54. Therefore, the final answer is 54 + 8 = 62. Since the given answer is 35, it is incorrect.

The given expression involves addition and multiplication. According to the order of operations, multiplication should be performed before addition. Therefore, we first multiply 1.4 by 5, which gives us 7. Then, we add 1.2 to the result, which gives us 8.2. Hence, the correct answer is 8.2.

The given expression involves addition and division. According to the order of operations, division should be performed before addition. So, first, we divide 1.6 by 2, which equals 0.8. Then, we add 8.4 to 0.8, resulting in 9.2. Therefore, the answer is 9.2.

The given expression involves addition, multiplication, and subtraction. Following the order of operations, we first perform the multiplications: 1.2 x 10 = 12 and 1.4 x 5 = 7. Then we perform the additions and subtractions: 5 + 12 - 7 = 10. Therefore, the answer is 10.

The given expression involves multiplication and addition operations. First, we perform the multiplication operation: 32 x 23 = 736. Then, we perform the multiplication operation: 4 x 2 = 8. Finally, we perform the addition operation: 736 + 8 = 744. However, the correct answer given is 80, which is incorrect. Therefore, the correct answer is not 80.

The given expression requires us to first perform the addition inside the parentheses, which results in 27. Then, we multiply this sum by 8, giving us a final answer of 216.

The given expression is a division problem. In the expression, we have 30 divided by the sum of 1.2 and 1.3. When we add 1.2 and 1.3, we get 2.5. So, the expression becomes 30 divided by 2.5. When we divide 30 by 2.5, the result is 12. Therefore, the answer to the expression is 12.

The given expression involves addition and division. According to the order of operations, division should be performed before addition. Therefore, first, we divide 52 by 2, which equals 26. Then, we add 10 to 26, resulting in 36. So, the correct answer is 36.

The given expression involves subtraction and addition operations. We start with 30 and subtract 12, which gives us 18. Then, we add 5 to 18, resulting in 23. Therefore, the correct answer is 23.
