1. ## So what's your purpose in maths then?

I have goals I want to achieve in maths. Specifically speaking: calculus; linear algebra; set theory; topology; differential geometry.

Now I was knockin' off this economics chick a while back and she goes, " to what end are you doing this?"

At the time, the answer I gave was because I want to. But any other answer would have made maths sound finite which is not the case.

Huh???????????????????

In the US, knocking off means killing. Does it have another meaning in England, or are you admitting to murder?

I'm very religious about definition and you've just given me an idea.

How would an alien civilisation understand our interpretation of advanced maths when definitions are involved?

For example, if you presented them with a pictorial picture of a circumference of a circle divided by its diameter they would conclude pi.

So a definition requires a diagram.

They might have a different name for it but the diagram says it all.

I am puzzled by why you would consider "circumference of a circle divided by its diameter" to be "advanced" mathematics!
(Not to mention a "pictorial picture"!)

If two people do not speak the same language then pictures will be needed. But if we assume first that the aliens have learned enough English to know what the words "diameter", "circumference", and "pi" mean no picture would be needed.

As to the original post: it sounds to me like the young lady is really asking "what do you plan to do with a math major"- what kind of job or profession? She might be thinking about what kind of income she could expect you to provide if she seriously considering you as a mate.

There could be many answers to that. I my self became a college teacher and made a liveable but not very high income. On the other hand, I know another math major who got into computers in the early seventies and now has a quite nice income!

Point taken. But why on earth is someone going to pay me for something they don't understand?

Seriously; I'm prepared to die penniless for what I believe in. Money has no value to me. It's a by-product of modern society.
