The Chief asked:


I wanted to start studying for my major in college which is finance and I was just wondering exactly what type of math do businessmen use in the field of finance and economics?

X-Malleus asked:


Pretty much exactly what the main question says. I have no idea what a finance charge is. For instance, would I be charged a finance charge if I charged a purchase, and then paid the balance immediately?

Any additional information that could be given would be great, as I’m considering getting my first credit card, and want to know everything I can so that I don’t get myself into trouble.
