The answer is: [D]: "Subtract 5 from 10" . ____________________________________ Explanation: ____________________________________ 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". ____________________________________________________
