1000-900x0.5= 50

I think

-400

50, obviously

It's 50 regardless of pemdas

I'm not good at maths.

Anyone who thinks it isn't 50 should go take math class again.

It's 200, whoever says anything else would probably fail middle school math.

nigger

Ebin guys, simply ebin

By mathematics rules the multiplication goes first so:
900*.5=450
And them subtract:
1000-450=550

>ITT people who think you can MULTIPLY something and get a SMALLER number as a result
Multiplication fucking means you add the number to itself n times, how the FUCK would it be smaller than the number you put in? Think before you post, morons.
The answer is -350

>mathematics

ayy nigga wtf is dat?

By the rules of my calculator on the desk, multiplication goes first and you can go fuck yourself.

I thought Kurisu was busy teaching mathematics in another thread already.

You should be able to solve this.

>Can't use a calculator correctly

Math is gay.

Anything multiplied by 0 is 0.

What is there to solve?

You can't multiply an odd number by a fraction.
Nice try though.

(1000-900)0.5

550

Why it sucked after the first couple eps.

That is true, however division and multiplication are inverses of each other.

In this case, you are multiplying by .5, equivilant fraction of 1/2

So to solve this, take half of 900, and subtract it from 1000, you get 550.

This is the kind of equation maths teachers love to throw out, since it teaches you the basics of order of operations.

On a side note, lots of shitty cheap calculators don't have order of operations included, so you need to be aware of it when writing up equations.

Order of operations. Multiplication before substracting.

1000-(900*0.5) = 550

Go back to middle school and pay attention this time.

>TFW I actually knew how to solve this

Pretty good for someone who failed remedial level math at college 2 times, and also dropped out of college algebra. I can't begin to tell you how retarded I am in math, I probably have a highschool freshman level math skill at best, maybe even middle school level. I'm pretty good in every other subject, but math, well I'm a literal retard if you ask me math problems....regardless of how "easy" you think it is.

Like I said, took me two and a half bloody years to pass a fucking math class at my college, couldn't even pass remedial level math courses.

>idiots telling retards they're bad elementary arithmetic

Freeza is about to head out to a remote planet with some of his trusty minions. However, he misplaced his keys and has to go back to find them. He tells his minions to wait and showed an open hand with five fingers.

How much time will Freeza spend before returning with his keys?

You should be able to solve this.

Five episodes

Five seasons

Five months.

>one hand
>five fingers
Trick question.

Sage and Report.
Fuck off back to Sup Forums with this offtopic meme shit

5 secondays

1000
900×0·5 = 0
1000-0 = 1000

It didn't say whose hand

It's Yamcha's hand, isn't it?

50

Oh god I feel so dumb

6?

>all these fags who answered 50
Oh Kosm

Now that's math I can understand, not this bullshit with triangle, x, a, etc.

Multiplication is just fancy counting.
Even if you count 0.5 two times, you still end up with 1.

>not realising "50" posts are bait
user you're the only one who is stupid here

>"Oh shit how did I get 50, I sure am stupid."
>"I-I was only baiting I swear."

You're a complete fucking moron if you think that anyone over the age of 12 messes up PEMDAS

If (1000 - 900) * .5 then 50
If 1000 - (900 * .5) then 550

You are missing your parentheses

>You are missing your parentheses
No.

Dude don't worry about it, most of that ability is determined by factors outside of your control. It's like crying over spelled milk at this point, there isn't much you can really do besides go through 10x the effort as everyone else to train yourself at being slightly good at basic shit which naturally gifted normies will always excel at anyway. Find something you're good at on your own and excel in that.

Can't wait for genetic engineering to kick off so that others don't get an unfair advantage or disadvantage for the entirety of their lives due to a bunch of unctrollable shit determined at birth.

Stay in school, friend

>Needing multiplication in parenthesis for it to go before subtraction.

I can't even tell if its trolling anymore or people are just morons.

You win for tonight Sup Forums i'm out.

What condition is there to ignore pemdas

pemdas privileges certain mathematical operations ahead of others.

In order to break down barriers one should take care to evenly distribute your operation usage.

You heard it here first pemdas is racist.

Why does Sup Forums as a whole never prove their work by subbing in different numbers?

1000-900*.5=50

X-900*.5=50 sub 1000 for X and solve

X-900=100, divide .5 from both sides

X=1000, add 900 to both sides

y'all had some shit math teachers

900x0 = 0
1000-0.5 = 999.5


Plebs

LOL u wot m8

>Americans trying to math

Aren't you supposed to be dreaming right now?

>being this retarded

>rules
They're arbitrary.
Did you fail all of elementary algebra?

that shit is like 3 generations away

>Can't wait for genetic engineering to kick off so that others don't get an unfair advantage or disadvantage for the entirety of their lives due to a bunch of unctrollable shit determined at birth.
except that's something probably literally only the rich will be able to afford

>X-900*.5=50, solve
k
>times both sides by 2
>2X-900=100
>add 900 to both sides
>2X = 1000
>divide .5 from both sides
>X=500
What's next?

The only correct answer.

>this whole fucking post
Fucking really?

Got a good chuckle out of me user, thank you.

I thought I was on Sup Forums for a moment there.

What would be the difference anyway?, basic shit like this is taught to even niggers and you have this thread as proof that some people are idiotic to a baffling degree.

HOLY SHIT ITS 2016 HOW CAN YOU BE RIGHT ON MY HUGBOX???

First: it is undeniable that these so-called rules are arbitrary (yes, agreed-upon correctness is still arbitrary)

Second: why are you stumped by simple algebra?

His was wrong, but that clearly was not your concern.

1000-900*.5=550

x = 1000

x - 900*0.5 = 550

-900*0.5 = 550 - x

900*0.5 = x - 550

450 = x - 550

x = 1000
education isn't intelligence
knowledge of arbitrary rules isn't intelligence

Who knows, maybe our rich overlords will do us a favour and let us die out, replacing the working class with machinery, so that no more children are born having to deal with inferiority to the rest of the populace. I'm not expecting someone to come out with a gene therapy next week that allows even detritus like me to become better, but it's a comforting thought that some of the children born in the future won't have to rely upon mere chance in order to be capable in this world.

The answer is 5000 you bakas

>They're arbitrary
You can call it whatever you want, it doesn't change the fact that the multiplication goes first except if there are parentheses elsewhere.

>American education

>2X-900=100
right here is the error
there is no "2X" because dividing the .5 cancels it out entirely on that side

it's fucking 5am and I'm on a mongolian underwater basket weaving forum arguing basic mathematics, I swear to god you guys are just trolling me.

I just can't .
I don't even.

>there is no "2X" because dividing the .5 cancels it out entirely on that side
except you're fucking wrong, the .5 doesn't apply to that whole side, only to the 900

only if it was (x-900)*0.5, but there's no parentheses so it only applies to the 900

This post has to be a troll

>there is no "2X" because dividing the .5 cancels it out entirely on that side
No, if you multiply both sides, you are supposed to multiply every single variable/digit, the .5 cancels out only for 900*.5, while the the newly formed (X / 0.5) becomes 2X.

>divides every term by .5
>forgets to divide the x
I like the dedication you're showing in making math fuck ups into bait posts if nothing else.


It's (X-(900*.5))*2 = 50*2

I am starting to think people don't know about order of operations because they have no idea how to work with monomes and polynomes. Seriously, just write it down as:
>a-bc=?
It's literally impossible to make a mistake when you see the underlying structure of the equation.

It's because you're still doing it wrong you brazilian subhuman, wheter you cook shit in a pan or in a pot the reason it tastes bad isn't the instrument you used it's because it's shit.
Holy shit.

1000 - 900 * 0.5 = 550
X - 900 * 0.5 = 550
X - 450 = 550
X = 550 + 450
X = 1000

Stupider than Wakaba.

I have absolutely no idea how you could possible think you're doing this right.
10/10 if you're trolling.

omg its 2016 why dont you think my vagina mathethics degree makes me smart?

Do you know what arbitrary means?

The "fact" that multiplication goes first is completely arbitrary.

(1000-900)*0.5
(100*0).5
0.5

Glad I'm not a stupid American.

Nice anime discussion though.

Kids needs to re stud their algebra
Engineers need to RTFM
Collegefags need to read a damned metrology book

>m/a/thematics

All of mathematics is "arbitrary". We decided how sets work, then we decided basic rules around sets. Starting from those rules, like for example Union and Difference between sets, we begun finding out other rules we could demonstrate starting out from our axioms.
It's from those very sets that we created relations, then functions (which are n+1 relations) and, well, everything else.

Arbitrary. And yet a valid model to describe reality.

i fucking hate you
