Re: How practical is a B.S. in Math?

I stuck with pure maths all the way through university. I had an almost snobbish aversion to any kind of maths that had any possible real-world application, because I was a twerp back in those days. So you don't have to "major" in anything in particular. Of course if you decide halfway th...

Re: What's your approach to digesting proofs?

Definitely TeX a proof that is important and you don't quite get. It takes more concentration to write down the symbols in TeX than it does if you're just writing on paper so it gives you a chance to think and digest what is going on in the proof. Plus you can make a .pdf of the important proofs wri...

Re: How practical is a B.S. in Math?

The double major in math and statistics wouldn't be a bad idea if that's what you're interested in. In my experience there is a pretty decent overlap between the two majors so it's closer to getting one degree and a minor in an unrelated field credit-wise.

Re: How practical is a B.S. in Math?

You can do a lot more than just get a Master's. A friend of mine is currently in his last year of a B.S. in Mathematics. He isn't planning on going to grad school. Instead, he is considering becoming an actuary or statistician, or maybe going into business finance. You can do a lot with a math degree.
