I know you faggots are going to say PEMDAS, but there is no hierarchy between multiplication and division [MD] so you have to solve it from left to right after you add (2+2). The problem is written poorly to create confusion, but that is the point of these facebook memes.

i recall someone or some program that treated the definition of the obelus differently to /. It stated that the obelus treated everything to the right and left as one expression but i can't recall where.

>>12252461
HAHAHAHAHAHA

>>12252477
if that is the case, then why does MDAS exist in PEMDAS ?

>>12252461
a(x + b)
= (ax + ab)

>Answer is 1

>>12252487
Because PEMDAS is some retarded acronym meant to help 4th graders remember order of operations?

Do you really think addition takes precedent over subtraction when mathematically they are the same fucking thing?

>>12252487
1+1-1+1

Is that 0 to you? MD are done at the same time, left to right THEN you do AS from left to right.

>>12252497
THAT MAKES SENSE

>>12252491
Funk you retard. Distribute the entire 8/2 not your arbitrary way of doing it.

>>12252495
but there's literally no order of operations that work like that as DM anad AS are equalized and work in order on an equaation by equation basis

so it should actually be:


BEDA
BEMS

>APL
8÷2×(2+2)
1

Operator precedence was the worst mistake in the history of math.

>>12252529
But you are not applying BODMAS rule
This is a wrong answer

the parenthesis adds a factor which cannot be ignored.
it is NOT 8/2*4 it is 8/2(4)
which means you need to solve it first. Remember how you deal with positive and negative values and parenthesis this is basic stuff.
-4=/=-(4)

>>12252580
the parenthesis doesn't do anything you fucking retard. 8/2*4 and 8/2(4) are the same expression.

SHUT THE FUCK UP RETARD

>>12252692
official laugh at poltards thread?

Pee, nas 'n easy...

4 threads and still going

fucking having the time of my life

>that american ranting about distributive properties that kept changing the equation to make it = 1

>>12252888
it's 1 tho....

>>12252910
just stop man

16

8/2•4
4•4
16

8/2(4) is 1

>>12252918
8/2(4) is different from 8/2•4

>>12252927
How is 4(4) 1?

>>12252934
2(4) has the brackets, so it is calculated first

>>12252952
The brackets aren't (2*4), retard.

>>12252957
what do you mean? it is 2*4. Just removing the brackets replaces it with multiplication which must be completed first

going off #5 of these poltard threads, anyone posting in them should lose the right to vote immediately

https://youtu.be/vaitsBUyiNQ

>>12253015
you mean #6

>>12252461
doesn't matter which way I slice it op, the answer is 16.

Ackshually division is just multiplication with a fraction, so they are equal.

>>12252605
i think hes saying it needs to be solved first internally, which gives the 4

>>12252887
This has got to be ironic

don't post this shit again, you've posted it at least 3 or 4 times in the last week

>>12254672
That's isn't the correct answer.
High IQs know it's 1.

>>12252477
I used PEMDAS and got 16. The rule for PEMDAS is multiplication OR division, whichever comes first. Same thing with addition OR subtraction.

imagine not being able to use bedmas

This is what American education gets you

Reading this thread is kinda surreal... I mean I know there are a lot of stupid people on the internet but people that would fail elementary school math? Is this the famous American education? The result is 16 you retards. Anyone failing math for 10yr olds should have all voting rights revoked... holy fucking shit O.O

>>12252461
The distributive form equivalent to this actually is:
4(2+2)
8+8
16

I know obelus had a bunch of different operations assigned to it through history and is elementary school notation, but where do you guys get the idea that in this sentence it is not equivalent to solidus, but equivalent to \frac{} ??

>>12252461

>>12252461
you faggots are all so stupid. 8/2(2+2)=1. Y'all fuckers really never even passed algebra i can tell. The fractional representation of this equation is 8 over 2(2+2), simplify if you get 4 over (2+2), aka 4 over 4, and then yousimplify it further and you get one.

>>12252487
Petition to change it to PEMA as multiplication and division are the same thing, same with subtraction and addition.

>>12252487
>why does MDAS exist in PEMDAS
It really doesn't. It's something that American schools came up with, but in some of them it's PEDMAS. I imagine that PEDMSA and PEMDSA and the likes could also exists. You're just used to the most popular one. People who can into math understand that the only thing that matters is the precedence of the operator:
>first powers
>second products
>third sums
Roots are fractional exponents, division is a fractional product, and subtractions are negative sums, so they all have the same precedent as the integer version. Solve things from left to right when precedence is the same and no problem can ever be ambiguous.

Why do these fucking threads always get so many replies? It's fucking boomer tier bait.

>>12256420
lmao using c++ for a scripting problem

>>12252487
P_E_MD_AS

>>12252461
Do you mean 8 / (2(2+2)) or (8/4)(2+2)? As it is written now it is ambiguous.

>>12257169

I hope you ran it in debug mode too

onefags BTFO!

>>12252461
First evaluate parenthesis
>2 + 2 = 4
Then evaluate multiplicatives (division is really just multiplication)
>8 / 2 = 8 * (1/2) = 4
>4 * 4 = 16

>>12253590
The only acceptable answer

This is simply an issue of notation. If it were written
(1/8)(2)(2+2)
there would be zero confusion. Parentheses first then left to fucking right.
(1/8)(2)(4)=(1/4)(4)=1

Now do the seven bridges of konigsberg

>>12258307

>>12258333
Am I misunderstanding the restrictions to this? You're suppose to visit the whole city crossing each bridge only once? Is it that you have to cross every bridge?

>>12258561
>Is it that you have to cross every bridge?
Yeh. Its impossible but you can do it on a torus, thats why I brought it up

>>12252461
ok, for the 16 fags that are dividing first:
lets rewrite the expression as 8/2(2+2)
lets divide
4/(2+2)
lets sum
4/4
lets divide
1
fuck off now, I divided first and still got 1

>>12258720
you're literally retarded anon, take a look at your steps again

>>12258723
there's literally nothing wrong you ape

The obelus is not the solidus and performs a different operation: line division. Check Rahn's Algebra.

Multiplication by juxtaposition is also a thing yo.

>>12258723
His steps are indeed retarded, however, he is still correct
