  • Actively wrong.

    PE(MD)(AS).

    Parenthesis comes first, do everything in each of them as though they were a whole equation to themselves.

    8/2(2+2) = 8/2(4)

    Then you do your exponents. The equation doesn’t have any, so we can go ahead and skip those.

    Multiplication and division are the same operation, just flipped around, so you go left to right and do those as you come across them. A number next to a parenthesis means multiplication, so to simplify:

    8/2(4) = 8/2x4

    8/2x4 = 4x4

    4x4 = 16

    Addition and subtraction don’t have any weird effects on the outcomes of each other, so you go left to right and do them as they come up. This equation has no more addition or subtraction to do, so we can consider what we have left our answer.

    Therefore: 8/2(2+2)=16

    This is straight from the textbook. You are wrong, and so are your purpose-built calculators.

    EDIT: Replaced * with x to avoid italicising.
