    you can cross off two of the choices if you can identify this as multiplying or adding multiply is show by a dot. add is shown by a + sign which is used here?

    now to pick the correct choice you have to learn (memorize) associate means "move parens" commutative means "change or switch the order" what is different between the two sides? order of the multiply or moving parens

    yea. associative means (a × b) × c = a × (b × c) commutative means a x b x c = b x c a
