Answer 3

Calculation:

To solve the equation 47 - 16 + 5 + 12 = 14, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's solve the equation step by step:

1. First, we perform the addition and subtraction from left to right: - 47 - 16 = 31 - 31 + 5 = 36 - 36 + 12 = 48

2. Now, let's check if the equation is true: - 48 = 14

Since 48 is not equal to 14, the equation is not true as it stands. We need to add parentheses to change the order of operations and make the equation true.

Revised Equation:

To make the equation true, we can add parentheses to group the numbers differently. Let's try different combinations:

1. (47 - 16) + 5 + 12 = 14 - (47 - 16) = 31 - 31 + 5 = 36 - 36 + 12 = 48

2. 47 - (16 + 5) + 12 = 14 - (16 + 5) = 21 - 47 - 21 = 26 - 26 + 12 = 38

3. 47 - 16 + (5 + 12) = 14 - (5 + 12) = 17 - 47 - 16 = 31 - 31 + 17 = 48

None of the combinations of parentheses make the equation equal to 14. Therefore, there is no way to add parentheses to make the equation true.

Conclusion: The equation 47 - 16 + 5 + 12 = 14 cannot be made true by adding parentheses.
