I have my degree in mathematics and I do system administration for a living!

As someone pointed out you can go into actuarial science (basically it's insurance statistical analysis). You have to take a series of exams to be fully licensed. The exams are very difficult but the pay is quite good.

You can work as an actuary even if you haven't passed all the exams, the company is mainly interested in the fact that you are pursuing the license. I tried going this route but the studying involved for the exams wasn't worth it to me personally.

There is an actuarial society based in Chicago, Illinois that is responsible for the administration of the exams.

I've had a number of engineers tell me you couldn't possibly have a better foundation for getting a Master's degree in engineering (I would expect an undergraduate degree in engineering might possibly be better!).
