Understanding the Expression

The given expression is $12 - 2 + \frac{2^2}{8}$. To evaluate this expression, we need to follow the order of operations (PEMDAS):

1. Parentheses: Evaluate expressions inside parentheses first.
2. Exponents: Evaluate any exponential expressions next.
3. Multiplication and Division: Evaluate multiplication and division operations from left to right.
4. Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Evaluating the Expression

Let's evaluate the expression step by step:

1. Exponents: $2^2 = 4$
2. Division: $\frac{4}{8} = 0.5$
3. Subtraction: $12 - 2 = 10$
4. Addition: $10 + 0.5 = 10.5$

The Result

The final result of the expression is $10.5$, not $10$. This means that the expression as it is written does not have a value of $10$.

What Needs to be Done?

To make the expression have a value of $10$, we need to modify it. Let's examine the options:

A. Add parentheses around $2^2 \div 8$: This would change the order of operations, but it would not affect the final result.

B. Add parentheses around $12 - 2$: This would change the order of operations, but it would not affect the final result.

C. Nothing needs to be done: This is incorrect, as the expression does not have a value of $10$.

D. Add parentheses: This is the correct option. We need to add parentheses to change the order of operations.

The Correct Solution

To make the expression have a value of $10$, we need to add parentheses to change the order of operations. Let's rewrite the expression:

$12 - 2 + \left(\frac{2^2}{8}\right)$

Now, let's evaluate the expression step by step:
