    If it’s 2(1 + 2) that’s considered one “term” and heavily implies that you should FOIL first before anything else. It isn’t the same as 2 * (2 + 1). Of course you wouldn’t likely get an equation like that without knowing “what” you’re doing, which would answer any ambiguity.

      2(1 + 2) does imply multiplication: 2 * (1 + 2). The reason it counts as one term, as I noted below, is because it is inside a two-dimensional fraction which has implicit parathenses in the numerator, denominator, and the fraction itself. The first equation is actually ((6) / (2(1 + 2))). When a fraction is written in two dimensions instead of a single string, the division between the numerator and the denominator is supposed to be done last.
