What do you learn in international business?

I'm a high school student and I keep switching on what type of major I would like to major in, in college. I know I want to do something involved with traveling like internationally. I've always wanted to see the world both good and bad, so I can get a better understanding of the world around us. So I'm studying french in school and I plan to study abroad for a few semesters in college. I'm also interested in math because I'm good at it, specifically algebra NOT geometry. Next year I'm taking IB pre-calc. So am I on the right track? What type of classes should I take at my school? What specifically would I learn in international business? What types of jobs could I get by majoring in international business? And how much money would I make? Please tell me about your personal experience.
