What is the result of the expression 15 - (6 + 4) × 2?

To evaluate the expression 15 - (6 + 4) × 2, follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right)).

First, calculate the expression inside the parentheses:

6 + 4 equals 10.

Next, substitute that value back into the expression:

15 - (10) × 2.

Now, perform the multiplication:

10 × 2 equals 20.

After that, replace the multiplication result into the expression:

15 - 20.

Finally, perform the subtraction:

15 - 20 results in -5.

It seems there was a misunderstanding in the proposed answer, as the calculated outcome is -5, not 5. If the intended result was meant to achieve a value of 5 under different circumstances, it is necessary to reassess the calculations and operations performed. However, the true result of the given expression based on standard mathematical principles is -5, and thus the answer does not match any of the listed choices accurately. Please review the expression and the operations applied to ensure clarity and correctness.
