I think Math and Computer Education systems would be a good combo. Computers and math go together very well. To master computer programming and such, you need very good analyzation skills and logic, which is what math teaches you. Accounting/Economics and Math are very good combinations too because economists use a lot of math in their studies of trends in economics, accountants too. Basically combine math with any of the other two and you’re set. Economics will lead you into any field of business or government positions, because it is a very broad topic. Computer information systems seems a little narrow as it is not offered in schools I know of. Better known as Computer science/software engineering? Math of course, is a classic major, and you can go into many technical fields with a degree in that, but I think Economics and Accounting is the most versataile of them all since the U.S. economy, for one, has around 70% of its workforce in the field of business.
