"Hello! I'm Dr. Huaizhong R, a passionate and experienced mathematics educator with a Ph.D. and capable of communicating math at any level, from K-12 math to research in my specialized area. I have over 15 years of teaching and tutoring experience at both high school and college levels, and I specialize in making complex math topics clear, logical, and approachable.

Whether you're tackling Algebra, Geometry, Calculus, Statistics, or preparing for AP exams or math competitions, I offer patient, personalized support that meets you where you are. I have taught at universities in the U.S. and internationally, and I understand the challenges students face when learning math—from foundational skills to advanced problem-solving.

My teaching philosophy centers around clarity, encouragement, and deep understanding. I take time to explain not just the "how," but also the "why" behind each concept. My goal is to help students build confidence, master concepts, and develop a lifelong appreciation for mathematics.

I can do both high school math (Algebra I/II, Geometry, Precalculus, AP Calculus, AP Statistics) and college math (Calculus I/II/III, Linear Algebra, Real/Complex Analysis, ODEs, Probability & Statistics). I also offer some test prep (SAT/ACT math, AP exams, AMC competitions) with flexible online sessions using clear visuals and step-by-step explanations

If you're looking for a patient and knowledgeable tutor who can help you truly understand math—not just memorize it—I’d be delighted to support your learning journey. Let’s tackle math together!" less...
