What can you do with a bachelors degree in math?

Math is one of the best majors a person can choose, imho.  It prepares you to think critically and it's not easy.

With a bachelor's in math you can go into several different fields, although you'll need more training before you jump in there.  You may be able to get this training on the job after being hired.  Many software engineers have a degree in math and many people in finance do too.  Obviously, these are lucrative fields.  You can also teach math and there's always demand for that.  The NSA is always hiring too!

Having a master's in math is better, of course, but you can get good jobs with just a bachelor's.
