Since the only (implied) operation in the expression is multiplication and since the Associative (grouping) Property applies to multiplication, one can change the grouping/parentheses in any way (add grouping, remove grouping, shift the grouping around) without changing the result! So these expressions, whose only difference is that the grouping shifted from being around the 7x to being around the xy, are equivalent!
