Literally a good understanding of high school mathematics (or, at least, what was high school mathematics back when I were a wee lad) is all you need. There may be a lot of math, and some of it may be used in ways you haven't encountered before, but none of it is tremendously difficult or impenetrable, and the unfamiliarity mostly boils down to "I didn't know you could do that" rather than "I don't know what's going on here".
