Well, if you have studied statics, dynamics, linear algebra, calculus, fluid mechanics, transport phenomena, introduction to differential equations, some complex analysis, continuum mechanics and computational physics (so basically the first year of physics or mechanical engineering at a university), then I don't think you need much more basic math and physics to understand any introduction to aerodynamics book. I recommend the books from J.D. Anderson, especially Fundamentals of Aerodynamics. Very well written.
