Use the correct order of operations, according to the mnemonic:
"PE MD AS".
The "P" stands for "parentheses", which takes top (first priority); and there are values in parentheses in this expression—specifically, the "(10 - 5)" . So the first step is to "subtract 5 from 10" —which is: "Answer choice: [D]".
Your error was starting at the beginning of the problem; and not using the "order of operations".
