No, it matters in the sense that if the main international system is already often ignored or downplayed, why would there be much respect for other international standards? There often isn't. It's rather a crapshoot at best.None of that has anything to do with order of operations, algebra, tan and cosin, etc. Literally all your saying is Americans use a different conversion. Congratulations, so do computers.
Its irrelevant to the discussion.
The great thing is, that particular detail of "PEMDAS" literally never came up for me, and I got through three years of Calculus. Anything left to implication can be misinterpreted.The ambiguity of this particular formula is how it is actually written, vs how it is interpreted.
Specifically, how people are taught to treat parenthesis isn't quite accurate. See, most places when they're teaching the math, teach you to see the 2(2+1) to read as 2x(2+1)- which, usually, is a correct read of it. But sometimes can get you in trouble.
Meanwhile, in actual order of operations reads #(#s) as all part of the parenthesis. If there is no operation between the first number and what's in the parenthesis, then you're supposed to read it as # iterations of the internal number.
2(2+1) could be just as accurately written as (2x2 + 1x2).
Not usually something that matters. Usually meaning 'exceptions exist' and this is one such exception.
The wrong way of reading parenthesis would, indeed, get a reading of 9. Because people look at it and interpret it (wrongly) as 6 ÷ 2 x (2 + 1), which absolutely comes out to 9.
While the accurate interpretation (as in, treating the 2 as connected to the parenthesis rather than a separate factor) would look something like 6 ÷ (2 x 2 + 1 x 2). Just as absolutely comes out to 1.
Thank you for coming to my Ted talk.
The government is sabotaging our education as part of a conspiracy to make us incapable of rising up against them.
That is way less of an exaggeration of a point than it should be. And I say that as someone that enjoyed and did well in school overall.We need to help the victims of the american school system whenever we find them.
There is no way that meme is real. I think, then I check to see if yes the phone calculators are in fact that wrong
... WTF
Phone calculators don't have to stand up to actual standards for things like this. So incorrect programming for crap like this is plausible, and sometimes inevitable.Phone calculators are, in fact, exactly that wrong.
Scientific calculators require a specific math-focused microchip, apparently, so they can calculate things properly.
