Anything from basic math to college-level calculus. I will review the work you are looking to do, solve it, and walk you through the detailed steps of how to solve it. I will encourage you to try a couple problems yourself as well to ensure that you retain the information. I am well versed in several learning styles (Visual, Auditory, Tactile) and can adapt to what works best for you, or help you find out which one works best for you as well as work with you in that style.
