Yes.
Because Americans can't into basic math operations.

>20 / 5 ( 2 * 2 )
>Brackets (2 * 2) = 4
>Division 20 / 5 = 4
>Multiplication 4 * 4 = 16
My answer is 16. I check it with wolfram alpha now and it says the answer is: https://www.wolframalpha.com/input/?i=20+%2F+5+(+2+*+2+)
= 16.
the equation is vague with pemdas.
It's an equation that starts arguments.
Apparently it takes away the advantage children with education have over those ghetto retard school children as parents don't understand this shit as they've been taught the old method.
It is supposed to make more abstract math subjects, high school and college level, easier due to the same thought process being used; seems like a bunch of gibberish to me though as the answers seem to be some 1984 newspeak bullshit.

How do you get one? I'm 31 and got 16 using "the old way"
That is 16, anyone who says otherwise it retarded.
by the way the "old way" (which is wrong objectively) is right > left
got 16 using BIDMAS
brackets, indicies, division, multiplication, addition, subtraction.

>1 = 16
>American education
Is it true that with PEMDAS, multiplication and division is to be done left to right, but before exponents?
Like in the equation 4/8(4-2), I would solve (4-2), then divide 4 by 8, and then multiply by the (2)?
>>80371447
BEMDAS you dumb Americunt
>>80371643
Yes it needs to be separated for very long equations. Obviously you can do it by a glance, but separating it with BEDMAS is necessary.

yeah thanks again, buddy. guess you really finished last lol 100%
This is why some pollock invented postfix.
I think saying the old way yields 1 should be the main takeaway. It's objectively false and seems like propaganda. I was educated in math at Catholic schools long before Common Core was even a thing and everyone I know would come to the same answer: 16.
It's shilling for Common Core.

20/5(2*2). Even if there were a proper space before the first bracket or like here when there is not. You still take it the fuck out. But you just killed the entire rest of equation or ignored shit

>>80371852
Never before exponents, and it's my understanding that if you only have division and multiplication the order doesn't matter.
old way:
20/(5*(2*2)) = 1
common core:
(20/5)*(2*2) = 16
This is what they do. I have no idea why though.
>>80373112
The numbers before the exponent are attached to the exponent but not in the way you retards think or troll. Exponents first niggers. Not mere division
This image is a fake. The original was a science bit (about the weather, I believe) and you can still see a bit of the original on the bit of the projection that is on the wall instead.
Common Core is still shit though, as an elementary school teacher I fucking hate it.
>>80370552
Mathematical ambiguity is easly solved by judicious use of parentheses. The problem on display is poorly formed and exists solely to see if you're using the OoP correctly even though mathematically speaking, division and multiplication are the same thing.

>Left to right
>Right to left
If you're not mathematically illiterate, you know it doesn't matter which direction you go but Everytime we have this thread there are hundreds of posts that give this same incorrect justification.
Division and multiplication are equal operations, neither gets precedence and which operation is where is irrelevant.
In the op's sentence, you treat the 20/5 as as multiplication by a fraction yielding 20*(1/5)*(2*2). In this way, it doesn't matter if your next step is 4* (4) or 20*(4/5) the answer will always be 16.
Also sage since this thread has been posted a million times and always hits the bump limit.

This.
>>80372290
thisd is retarded, because in the first operation you are dividing 20 by 5*2*2 and in the second you are multiplying 20 by (2*2) then you divide by 5...
fucking hell how is this hard?? been a game dev for 8 years now, the brackets are really important when you write math euations
/pol/ didn't go to high school
my fellow americans. do this for me, get a pad and pencil, and write a twenty over a line, then put a 5(2*2) under the line. i think this should explain how one might get one. i'll draw it out if anyone needs me to.

>>80371941
They treat everything to the right of the division sign as though it was the denominator of a fraction, but it shouldn't be treated as such here because it's written left to right. If they wanted it to be treated that way, they would've enclosed 5 ( 2 * 2 ) in brackets like:
20 / [ 5 ( 2 * 2 ) ]
>>The old way 1
How in what retarded old way it could be 1?
>>80373371
I don't know..
maybe mathematical equality?
Because of the order of operations, the correct answer is 16. After solving for the brackets, you go from left to right.

this is how one would get one. 5(2*2) = 20. 20 OVER 20 = 1.

>>80370552
Too many retards herw. Chink here too, both are correct because it is "subjective" / or it doesn't have real value and only has a value if we assign a value to it. Common core is bad because it destroys common sense (which isn't common) but is good because children now can learn that it is relative (mathematics, but it destrous math too)

20 / 5 (4)
4(4)

"old"
20 / 5 (2*2)
20 / 5 (4)
20 / 20
=1
What's not to understand? I personally don't like common core, but the rules are rather simple.
>>80374169
we were learnt bedmas as well
Ultimately, D and M hold equal precedence so we just do them in order
This becomes 20/5*4
=4*4
=16

It. Doesn't. Fucking. Materrrrrrr!
>>80370552
according to office spreadsheet application, you should put more () signs accordingly.
(20/5)(2*2)
or
20/(5*2*2)
Good lord, it's a slash, it's a denotation for a FRACTION, which you UNDO WITH A DIVISION.
If the equation was 20รท5(2*2), then the answer is 16.
BUT IT IS

There is no "old" way that would have evaluated that equation as:

Doing it that way would make absolutely no sense.
Now, there should probably not be a space between the 5 and the (2 * 2) to be completely syntactically correct in my opinion, but that is just nitpicking I suppose.
The correct way to evaluate this (obviously) is:
20 / 5 * (2*2)
=20 / 5 * (4)

The niggers and spics will come up with 16 and never gain employment except digging their own graves. Common Core won't dumb down whites, it will just finish off the browns (except Asians) and this is poetic justice!

Who writes a fraction line like a slash? Write it like normal people do and your problem is solved.
It's 16, what the fuck is wrong with you niggers?
You do brackets 1st, exponents second and then ,from left to right, you divide and multiply and then again, from left to write you add and subtract.
It isn't 20/(5*(2*2))
>>80375565
ฯ/5=ฯ*(1/5)
OK.
it's ambiguous. PEMDAS isn't a rule of mathematics.
the ambiguity is in whether the phrase is expressing *the quantity 20 divided by 5* times *the quantity 2 times 2*; or 20 divided by *the quantity 5 times the quantity 2 times 2*.
both have different answers. there is no right answer, it's ambiguous. it shouldn't be written like that, one should place parentheses somewhere so that the term is no longer ambiguous.
if you want to say "in the case of ambiguity, we will perform multiplication before any division", but that's not really any kind of logical necessity. division IS multiplication in the real numbers anyway.
>>80375644
Do you put brackets around the number 0 when you see it?

Not sure if you're saying that the "old" way is correct according to PEMDAS. The M and D are given the same priority and are then evaluated from left to right according to PEMDAS.
Therefore going from
=20 / 5 * 4
to
=20 / 20
is incorrect.

Yes, you do parentheses first. But only the 4 is inside the parentheses!
So let's evaluate (4).
(4) = 4.
Therefore,
20 / 5(4) = 20 / 5 * 4
The 5 is NOT in the parentheses. I don't know if this is a clever troll or you are just mathematically illiterate.

If that's the case then it's still 16 because you still have to do the division first.

x/ฯ=x*(1/ฯ) and this is not an inverse, it's a reciprocal.

This is fucking basic math. A fucking 7 years old kid could do it. Fuck, if you teach it right even a 4-5 years old. I mean, how can anyone do not do it?
I honestly can't tell why people are reading this as (20*(2*2))/5 when it is clearly 20/ (5(2*2)), the 5 and the bracket are connected (no space) and are clearly multiple of each other, to multiply the whole sum the 20 and 5 would need to be in a bracket.
I really feel for you idiots, when it switched to algebra and they introduced quadratics you must have felt so lost.
>>80376559

>>80373774
division and multiplication have the same value so you do them left to right. The same applies to addition and subtraction. The real answer here is 16 and that is how you would do it using the "old way".

>>80376787
They do equal the same thing. Two numbers together like 5(4) denotes simple multiplication the same way 5*4 does. The only way to get one is to write it (5*4) or (5(4)) if you like.

Is this really accurate? I think I learned in class that multiplication preceded division, but learned well-before common core was instituted that division is solved before multiplication if the operation is to the left.
Anyway, they shouldn't it's equally right, because exams will have one right answer and the student could give the wrong one thinking that it was correct because they didn't follow correctly the order of operations. If they accept multiple answers, that's even worse because it introduces a subjectivity in math that's not necessary.

>>80377144
it's not arbitrary, the 5 and the bracket are connected. Part of dealing with the bracket as the first step is to expand it outwards and remove it from the equation entirely.
20/5(2*2) -> 20/5(4) ->20/20 = 1
not
20/5(2*2) -> 20/5(4) -> 4(4) = 16
try making it 20/5+(2*2) and your method makes more sense as there is a seperation between the 5 and the bracket so it might be seen as two sums. Some people might still argue it as 20/9 as the brackets are still badly done, but it visibly shows how you've been taught to do it.

Funny shit, Ok enjoy your misdone taxes and shit, I'm sure the revenue service will forgive you when you try to explain order of operations to them.

This, the five is attached to the term inside the bracket, making it all one term.
The answer is 1 and will always be 1 even if some CAS software or programming language or nigger chokes on the problem.

Your bullshit is not an argument and you don't even know what a term is you dumb nigger.
Lol this shit is so funny. The answer is 1.

Explain how does the top input give an output of 1?
Its still 16 you retard.

No, if there is not a function inside a bracket, the bracket functionally does not exist. You would simplify by removing said bracket.
20 / 5 (4) = 20 / 5 * 4
>>80378641
also, no maths teacher would write it this way as it invites confusion. The question is either 20(2*2)/5 or 20/5 x (2*2), I'm not sure if you guys are using * as a multiplier or power sign desu.
Is getting 1 as an answer a purely American thing? I really don't understand this whole thread

The 4 is still in brackets. It's in his own image he didn't even rewrite it to a * like most you other idiots. He simply ignored his own rules.

Terms don't exist. There are four operations. Do them and be quiet. Numbers don't mean much but you can't ignore bedmas fractions reading orientations writing calculators addition is subtraction muliplication is division bullshit. Bed. Mas. You say some equations would need to change. Which ones? And do it. I brought up multiplying an inverse for pi rather than divide like i was told. Nobody explained themselves for shit
>>80379156
just let them be, it`s pointless.
>>80378697
What in the absolute fuck are you talking about? What did I say that has anything to do with what you just said? What is this a response to?
>>80379347
Single numbers in sane heads don't need brackets. First comes an operations signal or other bedmas function. (4) means 4

>Easier to work left to right
Maybe for some people. For me it makes no difference which side I work from. I always try to work a problem starting with the values that are easiest to compute.

You said "what" to my accusation of your being ignorant of metaphysics with a global earth smear. I explained your supposed reasoning for such
>>80379545
I didn't understand what were you saying or what specifically was it a response to within my post.
>>80379679
Of course you didn't. You look at math equations and put makeup mirrors in between shit
>>80378816
>The 5 is attached
There is no indication that this is the case and given that the creator of the sentence included parentheses already, it seems unlikely that they forgot how they work.
>>80379492
if you`re going with bedmas you have to solve the bracket. It doesn`t matter if there`s only a single digit left within it. It just doesn`t "dissapear" on its own so i don`t get what you`re talking about
I think i have a compromise...
1/2 = 'one half'
and
1 / 2 = 'one divided by two'
cuz fuck you รท symbol
>>80379723
I still do not understand how
>Oh my goodness. Look at this globe earth idiot
Is a valid response to:
>Well, I suppose that's an interesting way of looking at it, but it's not literally true, and I would be rather surprised if arithmetic was taught like this on a basic level anywhere, as you are going to see multiplication and division used in the same equations and it's easier to work from left to right than to make such conversions.
>>80379787
(4)=4
>>80379790
its the same
>>80379150
* Is always a multiplication symbol. ^ is for exponents
