Yeah, the biggest issue in the #Maths area - and I'm talking specifically about the order of operations rules here (check out my posts from yesterday) - is there's a whole BUNCH of youtubes from University people claiming it's ambiguous. It's HIGH SCHOOL Maths, which they have clearly forgotten - I've never seen a High School teacher get the answer wrong, or claim it's ambiguous, only University types (so I wish they'd stop making those damn misinformation video's!)

P.S. I also often see (often disparagingly) "this is a 5th grade Maths problem". No, it isn't. You don't get bracketed expressions with co-efficients until Year 7 (and by far the majority of people getting it wrong are following the Primary School interpretation, which only works if there's no co-efficients. This includes Texas Instruments calculators)
