what is the final solution to the common core problem?
>>110048695they should take a screenshot and ask AIidiots without phones
>>110048695Post common core slides, make fun on them online. Find the teachers responsible for it. Make fun of them online.
>>110048695obviously the solution to standardized education is more standardized education so that students understand why education has to be standardizedonly someone uneducated would find this confusing
>>110048695kek, this is like freedom units for algebra.
juxtaposition rules haven't been consistent.
>>110048783>standardized educationalgebra rules have been the same worldwide for centuries.so nothing to do with standardization, just us bureaucracy demanding random stuff to justify it's existence.
It's called MAGA math now.
>>110048862>t. uneducated
>>110048695There is nothing wrong with OP's pic. The problem is under specified so both solutions are correct.

(* (/ 20 5) 2 2)
Any answer is correct as long as you feel it is correct
>>110049061>The problem is under specified so both solutions are correct.The problem is perfectly specified. PEMDAS is law, motherfucker. Pretending there are multiple interpretations to a thing that has a single interpretation is the problem.
>>110048695obviously ameritardia education needs to put even more emphasis on the bible than on math and science

>>110049161
>>110048695
>>110048695same thing
>>110049148PEMDAS says "multiplication AND division", It doesn't say "first multiplication then division" or "first division then multiplication".
at this point it's been a decade since the first time I've seen this picture and I never found out the steps to get to 1
>>110049129>imagine thinking a slash symbol reaches into the future to grab numbers before evaluating left-to-right>ngmi
>>110049268correct, its just badly taught at school, the proper way is PE(MD)(AS)
>>110049298Correct, which means the problem is ambiguous.
>>110049275Do divisor first, assume (2 * 2) is part of it.
>>110049148The answer is ambiguous because division and multiplication are the same order.https://en.wikipedia.org/wiki/Order_of_operations#Mixed_division_and_multiplication
>>110049291how would you solve 5 (4) retard
>>11004869520/5*(2*2) = 1620/5(2*2) = 1
>>110048808>kek, this is like freedom units for algebra.It's educational water fluoridation.
>>110049061>>110049268>>110049334operators of the same precedence are applied left to right anons..
Both are correct because it's saying if you're gonna be an ambiguous nigger, then both answers are correct.
>>110049494>5(4) is 5*4 = 20>too bad the 5 is hitched to 20/ first, genius>20/5*4 != 20/(5*4)>go back to middle school or learn what an AST is
half of this thread are boomers running on pure 80's leaded fuel fumes right now

>>110049915just because it's ambiguous doesn't mean that it shouldn't be used
>>110049920>"it's ambiguous, which is why we should use it">bro is actively advocating for unreadable blueprints>literal definition of anti-math>pack it up anon, the cope is terminal
>>110049933it's only unreadable to retards who don't know how to do math
>>110049941>what color is your bugatti, nasa genius?>"ambiguity is fine actually">"everyone else is just dumb for wanting clear notation">seethe and dilate, enjoy your 1970s slide rulehaha, look, the bridge blueprints are totally ambiguous, but that doesn't mean we shouldn't build it!lmao, the prescription dosage is ambiguous, but that doesn't mean the patient shouldn't drink the whole bottle!
>>110049971again it's only ambiguous to people who don't know how to do math, go back to school
>>110049832that's not actually part of the order of operations anon. it's just a convention some people use.
>>110049227Why does everything outside of the parentheses have to happen before the division?6/2*3 is not the same as 6/(2*3)
>>110048695The common core answer is right, though.
>>110049832That would make the phone calculation in >>110049227Correct, and the calculator incorrect. This is my assumption as well but others seem to think otherwise
>>110049497 what you're thinking is20/5(2*2) = 1620/(5(2*2)) = 1You're hallucinating another pair of parentheses because you don't understand that x(y) is shorthand for x*y.
>>1100501016/2*3 is not the same as 6/(2*3) but it's also not the same as (6/2)*3
>>110050131x(y) binds tighter than x*y

>>110050027Stopping on red isn't part of driving, officer. It's just a convention some people use.
>>110049227>>110049334>Shitty offbrand calculators get it wrong.Texas Instruments is overpriced bronze age technology, but at least their products actually work.>>110050027Several operations need to be done left to right to function. You wouldn't say that 12-2+3 is 7. That's obviously retarded. It's likewise absolute retardation to say that you don't need to evaluate left to right for some tiers of operations because you don't feel like it.>>110049898We've had the ability to generate proper math functions in electronic documents for damn near as long as computerized documents have existed, and it's trivial to align this stuff on an actual printing press. They made special sorts specifically for this back in the 1800s.The rest of the world that actually gives a shit about clarity has defined operations as left to right for anything where it could matter. Nobody should give a shit about what some retarded cyka blyats did in the 50s because commies couldn't figure out how to print a book correctly.
>>110048695>common corenigger math. because they couldnt understand order of operations so instead of failing niggers they jsut changed the rules so more of the dumb fucking apes pass
>>110050262x(y) is literally x * y. There's no difference between them whatsoever.
the autistic deal poorly with ambiguity. posing an ambiguous problem to them in a system they think is set in stone is very amusing.
>>110050405yes there is, you even typed it
>itt: boomers rage baiting>on /g/trolling outside of /b/ is against the rules
>>110050262that equally just a convention without universal acceptance (but a correct one)
>>110049148>PEMDASpemdas doesn't say e right to left, md left to right.
>>110049148>PEMDAS is law, motherfuckeryou know, this might be the most childish thing i've read all week.consider the state of mind of someone this dedicated to shorthands taught in grade school
>>110050393>Several operations need to be done left to right to function. You wouldn't say that 12-2+3 is 7.That's 13 no matter what order it is you retard. No operation needs to be done from left to right.
>>110050393If juxtaposition is *, then it's 16, if juxtaposition is another operator you do before MD, then it's 1.The error isn't direction, the error is that there's a special rule (the wrong answer is harder to get, and is intentional).
>>110050262>x(y) binds tighter than x*yI think it's better to prohibit it, since it looks like a function. my 2 cents.
