To find the value of the expression 8 × (2 + 6) - 10, we begin by simplifying the expression step-by-step, following the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. First, we address the parentheses: (2 + 6) evaluates to 8.

2. Next, we substitute this value back into the expression:

8 × 8 - 10.

3. Now we carry out the multiplication: 8 × 8 equals 64.

4. Finally, we perform the subtraction: 64 - 10 gives us a result of 54.

Thus, the correct answer to the expression is 54, making it evident why this is the right choice. This calculation illustrates the importance of properly following the order of operations to arrive at the correct result.
