Well, Yas Forums? Your answer?

20/5=4
2x2=4
4(4)
=16
According to common core at least. Does CC not recognize PEMDAS?

what
it's 1

16 is the correct answer. In order for it to be 1 the 5 needs to be in the same parenthesis as 2*2 ie 20/(5*2*2).

Aren't parentheses higher priority than operations?

What?

This. The grouping matters.

No, they expect kids to get confused. They gave up on teaching negro children and instead are "equalizing" math by ensuring nobody understands it.

I made my Gf do this problem because I wanted to see which she would come up with.

She needed pencil and paper, okay whatever.
20/5(2*2)
4+10+4
18

Naturally I handle all of the finances

$Tree Fiddy

Wtf it was never 1. 16 is the only valid answer.

I’m just fucking with you. The only way you could get that is if you somehow confused distribution into the equation.

Parentheses first. (2x2)=4. Then multiply the 5 and the (4), because they're next to each other. You end up with 20. 20/20=1

AWAY from the CHILDREN
But yeah it's 1

This

PEMDAS?
20 / 5 (2 * 2)
> Parenthesis
20 / 5 (4)
>Exponents
n/a
>Multiplication
>Division
20 / 5 (4)
4 (4)
16

How do you NOT arrive at 16?

Ambiguous. Mathematics is basically a more rigorous philosophy and mathematical notation is merely a vehicle for expressing certain ideas. Trying to get a correct answer from something that is ambiguous and poorly communicated is fruitless if we don't understand the intention of the person who designed the question.

Day gorillion and ten: Still a nothingburger... *yawn*

The answer is 16.
PEMDAS is partially a rule of thumb, invented because it sounds like a word so it's easy to remember, multiplication and division both take equal precedence. When in doubt, you just default to doing the operations left to right.
However, the way the equation is written is really bad in the first place, this sort of situation shouldn't really happen, and it's kind of stupid to teach, because any maths class obviously will use parenthesis to some degree to avoid such ambiguity.

5(4) is still a parenthetical operation, brainlet

Low quality bait

Is this woke anticolonial maths? Because she looks fat and the word equally is mentioned.

>using PEMDAS
>doesnt even do the multiplication when its the multiplication step

the problem is that the multiplication and division happen simultaneously so either answer could be correct depending on your interpretation. because the 5 isn't also in parenthesis however the answer is 16.

That’s not how math works nigger

>20 / 5 (4)
This step right here. Some assume this means you multiply 5 and 4 despite no sign being present connecting the two.

Arghhh stop writing quotients like that and stop using the asterisk for multiplication fuck that's just wrong

No, the problem is that they got "the old way" wrong. The only answer is 16. Evaluate parenthetical first, then multiplication and division simultaneously left to right. 16 is the answer.

You got bigger things in Brazil to worry about than education, Jose.

Only sick greenposters believe the answer is 16. Healthy minds know it's 1.

>Thinking 20 over 5*4 is anything but 1

The state of the shit hanging from the wall and the alignment of the projector to the screen speaks to her level of competence.

This. What lazy teacher couldn’t do the basic work to format it properly.

Was never in common core. Obviously the answer is 16, this is just common core propaganda. All other answers are brainlets

t. retard
5(4) is the exact same as 5*4
Did you just see parentheses and assume that they must then fit into your elementary school fucking designed system made so you could better remember a simple series of steps?

>t. Stupidest bastard in existence

just wait till CommonCore people start working for TESLA or BOEING..

good luck with that..

Don't you have something in mathematics called "priorities in operation" ?
It simplifies everything.

kek

The only answer is 16

Operations inside the parentheses go first.

Multiplication and division are the same thing. E.g. multiplying by five is equal to dividing by 0.2. Multiplication and division have the same priority and so happen left to right.

Dude...

Think of it like
20 / (5(2*2))

Because you can always rerewrite a number as its root multiplications. for example, you can always replace 20 with (2*2*5). Whenever multiplications are right next to each other, consider them a single number.

5(2*2) is the same as (5(2*2))
Implicit operations take maximum possible precedence

I know you are trolling but i still hate you

You don't divide by a partial divisor, absolute brainlet. Imagine the 5 or 4 was a variable, see how retarded you are

20/5 (2*2)
20/5 * (2*2)
20/5 * 4
4 * 4
16

in writing that's the logical answer. if people come to multiple conclusions from the same basic sentence the writer is at least part of the problem

It's hard to tell, there are people this stupid

PEMDAS goes left to right, nigger

Not right to left. You're either a jew or retarded.

no.

PE(MD)(AS)
you fucking niggers, if its in the same priority it proceeds from left to right

Both aren't correct wtf
The correct is 16

You clearly lack a grade school understanding of math.

wolframalpha.com/input/?i=20/5(2*2)

Self confirmed retard

they never will

Idiot

Another elf confirmed retard

You're an absolute retard, you can't divide by a partial divisor

It's 16 you fucking retards. Multiplication and or division left to right.

You don't know how to read implicit operations. Draw it the "old way" with the numerators on top and denominator on the bottom

(20/5)*(2*2)
or
20/(5*(2*2))

Feed it into a calculator and it'll default to the first one, returning 16 as per PEMDAS. The bottom one is how you arrive at 1.

>thinking 5(4) isn't the same as 5*4

Please excuse my dear aunt sally, niggerfaggot.

The equation is ambiguous. Don't use an in-line division symbol like that.

Attached: 1583820886279.png (618x618, 90.48K)

but its not 20 over 5 times 4
its 20 divided by 5 times 4
if it was over 5 times 4 it would be written as such
(20) / (5*4) is not the same as 20 / 5 * 4

Yo how the fuck you do that green shit

order of operations had Yas Forums stumped even back when your fathers were posting here in 2006

It's simply written poorly. It should be dawn out, not typed.

It should be like a fraction:

20
______
5(2 x 2)

Yeah, no. There aren't implied parentheses just because you're a retard who doesn't know basic math. If it were 20/(5*2*2) then it would be 1. As it's not, it's not.

I linked to Wolfram Alpha before. I suppose you think that's wrong too?

In reality I'm not trolling and you're wrong.

The problem is that you are multiplying 4 with the wrong number, you should multiply it with 20, not 5.

>dude just fucking do it a different way than the way you're supposed to do it and you get the answer I got, wrongly

20/5 = 20 x (1/5)
20 x (1/5) x (2 X 2)
20 x (1/5 ) x (4)
4 x 4 = 16
Actually , the spacing is retarded but for the answer to be 1 you need to rewrite the 5 inside a parenthesis with the (2x2) to indicate that both have a common numerator of 1.
20 ÷ (5 x (2 X 2)) = 1
20 ÷ 5 (2x2) = 16

It's not ambiguous at all, any possible operations on either side of a division need to be completed before dividing. Basic algebra

This is right.

>multiplication is different than division
no.

>mutts can't into math

It was 5(2+2) as a denominator, that's 20, fuckwit

You have to do every operation necessary to drop the parentheses. 5*4 is not the same as 5(4) on an operational standpoint.

It isn't written poorly, because that's exactly how it should be read

HOORAY FOR NEW MATH!

No. You made that up.

Why

My input is the exact problem you halfwit.

It's the only way to do it, dumbass that's what the problem looks like written in a different syntax

Retard

But I *coof* didn't

The screen isnt even projected right

You must never have taken any math class at the university level if you think calculators are never used.

The teacher is a tard for not putting it in a proper format.

No, it isn't. that's the problem. You're an idiot who doesn't know about having to do implied multiplication on parentheticals before any further steps

No it is not, dumbass. You REWROTE it that way.
It's an inline division symbol. Multiplication and division take equal priority, and when the order is not otherwise specified, left comes before right.

Attached: retard.png (297x123, 3.34K)

I always used a scientific calculator. The only time I really used a graphing calculator was AP Calc.

They used common core to judge the proper alignment angle, got 20 degrees instead of 0

>denominator
where?

Haha, the step-by-step solution goes straight to the answer because it's so obvious if your mind hasn't been poisoned by PEMDAS.

that is literally just wrong.
there are some wrong posts in this thread, but that it the wrongest.

Fuck I didn’t realize how dumb some of you are xD

If that was the intended problem it would be written as 20/(5(2*2)) to show that 20 is being divided by the rest of the expression.

You're wrong.

American education. If you use in-line division like that, multiplication and division have the same precedence. The equation is ambiguous. Writing it with a vinculum, like say, anyone with a proper mathematical education, would clear up any confusion.

Attached: 1577058440184.jpg (824x678, 80.23K)

What's 1/2/3?

It's not ambiguous, a / only effect the number after it, if the number after it is in a parenthesis it affects the value of the parenthesis, a dividing line means all numbers above it divided by all numbers below it.

The right side of the inline division is the denominator, the whole mathematical phrase, not just the first number

Just stop, retard.

If you think 20/5(2*2) is a university math level you are a dumb nigger.

Mmmmmm Ting!

Attached: beatDownBabylon.jpg (480x360, 21.33K)

1/2/3 is evaluated the same as (1/2)/3

The old way would also result in 16, anyone who says 1 should go back to grade school or be shot.

Everything to the right of the division symbol is the denominator, you stupid koala fucker

maths is rayciss

if it wasean to represent a fraction it would have literally been written
(20)/(5 (2+2))
agreed

No it isn't, you rewrote it that way!
