This is literally a boomer Facebook meme. Someone would post it and they would all do the math in diffrent ways and get diffrent wrong answers because they have been out of school long enough to forget it
At least those ones spark a mildly interesting conversation about implicit multiplication and why we have the order of operations. Ian's version is just silly and rather sad
We all learned it. We have all forgotten plenty of thr stuff we haven't kept up practicing. It is their unwillingness to accept that they could be wrong and lead posion lack of creative thinking that is the mind killer here
