We have several team members with their PhD or Masters in Mathematics,

Yes, I've seen those type of people getting order of operations wrong too, because they've forgotten their High School Maths. I've never seen a High School teacher get it wrong.

@FishFace@ioc.exchange I arrived from his very interesting comments on a Github issue where he seemed to insist that all calculators, mathematicians, and engineers should defer to his superior authority as a "High School Maths teacher": https://github.com/dotnet/runtime/issues/92849#issuecomment-1741825708 He repeatedly shared his Mastodon thread as supposedly sourced evidence. From what I gather, he fundamentally misunderstands what brackets even are. He believes that brackets *are* the distributive property, so, in his head, BEMDAS is really DEMDAS.

@SmartmanApps@dotnet.social The third image doesn't have your so-called, literal "×" "multiplication" at all, so there is no meaningful distinction between the "B", "E", and "M" of BEMDAS that can be pointed out here. The fourth image... read the fourth image again. = 5[3 + (14)] = 5[17] = 85 Notice how they didn't follow your version of BEMDAS. Instead of applying the Distributive "Law" and expanding 5[3 + (14)] into 5(3) + 5(14)... they did *addition* first?! Whaaaatt? But "A" is way after "B" in BEMDAS!
