1. It has no practical application, why can't people who work (professionally I mean) in pure maths do something that actually benefits people.
Yes, I know that it helps to explain things like science which have practical application, but we don't need pure maths to help with that once the problem (or whatever it is) is found because people can work out the maths needed without worrying about the silly things like mathematical proof.
Just to clarify my stance, I think if something has real-world application, I no longer consider it to be 'pure maths'. So please don't say things like 'it is useful for solving problems in physics to do with black holes (or whatever)' because then it would no longer be pure maths.
Other than for 'fun', what is the point in pure maths?
EDIT:
Okay, to clarify further. I think 'pure maths' is when people try to prove things that, for all intents and purposes, are self-evidently true. It is impossible to prove something without making assumptions, so mathematical proof is no more valid than scientific proof just because it makes different assumptions. Also, when people work on problems with numbers or algebra (or whatever) that they can't clearly see an application for (an application being something that would benefit other people). Just because applications are often found later, that doesn't justify finding out the methods used earlier on, because those same methods could have been discovered when the real-life problem arose.
2. Can you give me an example of some "pure" maths that has no real world application so that I can respond to your survey
3. So you're asking whether pure maths has a 'real world' application, defining pure maths to be maths that has no 'real world' application?

Also, what TenOfThem said.
4. whats the point in life?
5. A sly way for teachers to mentally torture their students
6. First of all it's "of" not "in", and as above, pretty much all maths can be applied, just maybe some can only be applied at very high levels.

Also just to illustrate, 1+1=2 in this context has no real life application and is therefore "pure" as if you think about it, it doesn't really mean anything - 1 what? 2 what? But when you apply this to counting it is no longer pure. So iy is clear from this rather mundane that pure maths is only pure if we do not give it application or have thus far not found any application. This is not the same as saying there exists no application.

Research mathematics has quite a long cycle from inception to application. For example, complex analysis was being developed some hundred and fifty years ago, and didn't find real application until decades afterwards. You can find lots of similar examples to this, where a new development doesn't immediately appear applicable, for example group theory, and even more recently the theory of fractal shapes. History shows us that we can be confident that new mathematical breakthroughs may well prove useful, even if it may not be be until long after our deaths. So I disagree with you that it doesn't benefit people; if mathematicians hadn't worked to discover new - not yet applicable - mathematics, your life would look totally different.

I guess my conclusion is that if we take your definition, then there's no such thing as pure maths!
8. Pure maths is learning the methods. There may or may not be applications and you may or may not need it in life.

For example dot producting vectors, I thought, what is that useful for, and my teacher asked if I were familiar with Work being the product of Force and distance. The application of this method comes in at Mechanics 2. So you may not thing you need it, trying to understand the method helps but pure maths is just that, pure and methodical.

"It's extraordinary, it's always the children who say 'Sir, sir, what's the point of geometry, or what's the point of Latin,' that end up having no job, being alcoholic, and they don't notice that the ones who actually find knowledge for its own sake, and pleasure in information, in history, in the world and nature around us, actually getting on and DOING things with their ****ing lives... it's an odd thing." - Stephen Fry.

As for proofs, in maths it's just not good enough to just say, "it works", we have to have proofs - otherwise how can you be certain that whatever theorem, equation etc works?

This. Something doesn't have to have a point for it to be studied. If someone is curious about certain number patterns or logical systems then they will study it regardless of whether it has any real life applications because they just want to know
11. It's ****ing enjoyable
12. Pure maths, or understanding the underlying structurse in mathematics, is as close as we'll ever come to understanding the underlying structure of the universe

Finding the dot product of two vectors isn't pure maths

As for the OP, if pure maths is no longer allowed to be classed as such when it starts being useful, obviously no pure maths will be 'useful' by your definition.

Many parts of applied maths originated in pure maths. I don't know how much you know about calculus but I can't even begin to describe how useful it is in applied maths. The idea was developed through concepts in pure maths.

The point can be many. In topology it is the element of an open set.

It is at a-level I can appreciate its not the same at Uni

No, I'm asking what the point of it is. It seems selfish (that probably isn't the right word though) to study something just because you enjoy it.
I am well aware that eventually much pure maths has applications, but can't we just 'come up' with that mathematics when the real-world problem arises?

I only know about, like differentiation and integration but I think that makes more sense in an applied context (where the variables actually mean something i.e. displacement, velocity, acceleration, rate of change of acceleration with respect to time) than in a core context.
My point is, it didn't need to be discovered until people realised the real-world problems.
A lot of maths was learnt in a real-world context was it not? 'Pure' maths came after 'science' or 'physics' or 'applied maths' whatever you want to call it. I know this doesn't mean much, but still...

the point of pure maths is find real world applications, so by defining real world applications as not being pure maths you are saying that once pure maths does its purpose it is no longer pure maths, which is an invalid argument

What is called "pure" maths at A-level, isn't pure maths
