This is why it's a troll. Apparently somewhere along the way--possibly a generational change or a widespread math-teaching policy change--what constitutes "resolving the parenthetical" involves.
I'm going to guess I'm older than you, because that is how this usually goes. To me, resolving the parenthetical (which is PEMDAS priority numero uno) means resolving that chunk together, which includes the 2 stuck to the outside of the parenthesis. That "clause" becomes "2 * 1 + 2 * 2." PEMDAS again, and that portion becomes "2 + 4." Solve, "=6."
YM obviously MV, but I find it very odd to not treat the parenthetical as a whole clause, in the absence of an operator between the 2 and the parenthesis.
Now, I'm no slouch. SAT/GMAT scores with math in the top 1%, back in the day, and having tutored statistics at the graduate level. So I don't think this is me remembering it wrong. Somehow at one point I managed to not get these questions wrong on standardized testing, relying on this method.
My best guess is some time between scenes, what was considered SOP, or at least was taught by primary school math teachers, changed. Maybe it wasn't even a universal change, leaving some people to know it one way, and some people to know it another. What you're left with is a "Gif/Jif" fight where people are largely just so used to their certainty, that the other guy's usage causes them frustration and discomfort.
