>>143533964
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.

>>143534086
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.
>>
>>143533804

Order of operations. Multiplication before substracting.

1000-(900*0.5) = 550

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.

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

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.

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.

Are you a fucking 12 year old?
Yes, it's arbitrary. Yes, math would be equally as consistent if the convention was that (without parantheses) addition comes before multiplication.

That does NOT mean that you can take an equation and just decide to follow different rules. I mean you can, and your results will be consistent, but completely incompatible with everyone else. Basically, you'd be a huge idiot.

It's the same thing with language. The fact that "cloud" means "that white fluffy stuff in the sky" and not "the male reproductive organ" is completely arbitrary. But if you go around shouting that clouds are dicks because you decided so, people will think you're a fucking moron.

>Axioms are fallacious
Why? As long as we don't rely on too many of them and we are absolutely sure they are extremely simple (aka, absolutely impossible to demonstrate), there is no problem. You can actually build extremely complex and useful mathematics with them.

Take vectors (as in, mathematical vectors, matrixes with shape 1xa or ax1). You start by defining two simple axioms: that you are allowed to sum two vectors and that you can multiply a vector for a constant value (you also define how this is done). With this simple idea, you create everything else. And as much as you want to make axioms to sound "fallacious", the monitor you are working with right now is actually working using vector and matrices math.
>>
>>143536416
Well, you sound like a little kid who can't even memorize one simple rule.
Mathematicians only don't use paranthesis for multiplications, cause it's a lot easier to read in longer equations and a pain in the ass to write every time.

>1000-900x0.5= 50

on first glance this is how it looks. however math is funny in that it has an order. Multiplication/Division before Addition/subtraction

So it's really 1000-(900*0.5) = 1000-450 = 550

I admit I was a little stuck.

Not my fault people wanted to shove me into a special school only because of "something" I apparently had in my head ever since the moment I was born and it turns out, I actually never had anything wrong with me and I spent the entirety of my childhood on a shit ass special needs school that teached fuck all, only the most basic of basic shit, while having my hair tugged out from kids that actually had their very own issues and needed special care (which I can't blame), which my mother decided to take me out of only to end up my remaining days in house helping around and spend another part of my childhood only learning what I was subjected to in the internet.

Now thanks to THAT, shit that I should have learned since very young, now I have to make up for lost time as a grown person, trying to fix the shitty childhood I once had education wise.

And apparently, that school was so shitty, I'm pretty much declared as someone who doesn't even HAVE any studies and apparently can't even write even though I can. And that school even seized to exist and any remaining proof that I may have of having done any sort of studies are now hidden behind closed doors, if there are even any.

Irony of all ironies, people like to call me smart for whatever reason when the truth is, I still struggle with some basic math problems that go beyond what I haven't learned in that lousy school. I know I'm not a retard, but it still feels pretty damn embarrassing to not even have any sort of studies backing me up.

The only thing I learned about all this is being apathetic as fuck while trying to be open minded about everyone, regardless of who they are.

tl;dr don't be like me

Mathematicians don't ever use order of operation rules though, the only time you'll ever have to use them is in middle school "maths" problems designed specifically for them. Such problems don't arise naturally in mathematics or any applications.

That anon may be a complete retard, but he's right about it being arbitrary. The only reason it's like that is that it's much easier to write polynomial expansions like that. You could, if you wanted to, decide that addition comes first when there are no parantheses. Everything would still be completely consistent.
>>
>>143539122
What are you talking about? Of course they do. It's literally impossible NOT to use them, since some set of operation order is required unless you use parantheses for every single operation. See >>143539271
Try writing a polynomial expansion without assuming that multiplication comes before addition. It's just that order of operations is so fucking simple that it's a complete non-issue once you get past grade school math. It's not that it doesn't exist anymore.

According to mathematical theory, the sum of all natural numbers (not all positive reals >>143541807 you retard) equal a negative twelfth.

The sum diverges you fucking idiot. The Riemann zeta equals the sum for real part of the argument larger than 1 but an analytic continuation is possible to the entire complex plane, which assigns values to the zeta function. Outside of the domain of definition for the sum the zeta function does not equal it.

Flooring, or truncating, a number gives the greatest integer that is equal to or less than that number.

Floor function: ⌊x⌋. So ⌊3⌋ = 3, ⌊2.9⌋ = 2, ⌊-1.8⌋ = -2, etc.

Similarly, there's also a ceiling function ⌈x⌉, which gives the smallest integer that is equal to or greater than the number. ⌈3⌉ = 3, ⌈3.1⌉ = 4, ⌈-1.2⌉ = -1, etc.

1/2^x = 2^(-x)
substitute -x=u
the integral of -2^u is - 2^u/ln(2)
after resubstituting -x we get 1/(2^(x) ln(2))

This is very basic.

>The sum does not depend on n
The value of the sum does not, but each part of the sum (of which there are infinitely many) does.
Therefore it must be possible to use a function to represent the sum and calculate it using an integral.

Yes.
There must be a function where the integral is equal to the sum within the same bounds and I can show you that:
substitute (2^n) as -x
So we the function -1/x, this function should already be the anti-derivative, therefore we just put in our values 1 and infinity, subtract and we get 1, just like what is apparently correct.
Now the obvious question is whether you can formulate a set of standard substitutions.
Which is none of my concern, since I have shown my point and this is a massive waste of time.

IMO the best way to understand math is a combination of 'mindless' memorization and deliberate analysis. Lacking either one or he other will cripple you in different ways. I used to lean too far to the latter side, resulting in me figuring out shit from scratch each time I encountered it if I couldn't remember, which was slower and made it more difficult to avoid errors.

>>143545637
Wrong. Just draw the forces.

In left the ball is part of the beaker system so the only force it can add is its gravity force (very small).

In the right beaker there must be a force pushing the beaker downwards equal to the bouyancy force (one of Newton's laws).

As a ping-pong ball is lighter than the water of the same volume, a bigger force is exerted on the right beaker and it will go down.

Because that follows from the definition and literally no one except you needed to realize this in order to understand exp.

It is. If long division can justify 1/3=0.333... then it can also justify 1/9=0.111... Two statements are equivalent.
So far the only satisfactory proof for 1 = 0.999.... is by summing the series that represents 0.999... or through defining the reals and proving that infinitesimal quantities don't exist in R. But of course I wouldn't expect the average /a/non to know this.

Depends just how bad you are.

If you can't deal with calculus, okay, sure, you can still be intelligent.

If you can't deal with algebra, some part of your brain is inferior to an average adult's.

If you can't deal with arithmetic, you are genuinely retarded.

I'm studying Engineering, 4th year Mech. I have never used series outside of our Math courses. Never ever. Not even when we were studying waves.
Maybe if I were going for my Masters or a PHD I would use it, but a BA w/ H, no.

No one said anything about me you retard. Given how you're too retarded to understand how Fourier series is useful in engineering I wouldn't be surprised if you don't know how to read as well.

If n is a natural number it is either even or odd.

Suppose n is even.
Then n = 2k where k is some natural number.
(1+n)(-n)(-1) = (1 + 2k)(-2k)(-1)
= 2k + 4k^2
= 2(k + 4k^2)
Here we easily see 2 divides this. 2 is prime.

Suppose n is odd.
Then n = 2k + 1.
(1 + 2k +1)(-(2k + 1))(-1) = 4k + 4k^2 + 2 + 2k
= 6k + 4k^2 + 2
= 2(3k + 2k^2 + 1)
This is also divisible by 2, a prime number.

If pemdas must be followed how the fuck do you solve something like 10 - 90 x 0.5 + 606 / 59 x 0.5 + 502 + 11 x 5^5 / 9 - 10000 x (50 - 2) - 29 + 33 x (0.5 + 502 + 11 x 5^5 / 9 - 10000 x (50 - 2) - 29 + 33) - 0.5 + 502 + 11 x 5^5 / 9 - 10000 x (50 - 2) - 29 + 33 without using a calculator? You're gonna be jumping all over the place just to find which operation to deal with first
