Hello, I’m Steve Roberts, Mr. X, Mentor of Mathematics. I created this website to help both students and teachers. Students need to understand the principles of mathematics and teachers need every resource they can get to convey the essence of those principles. I emphasize practice. My goal is to help everyone to use the language of numbers more effectively. There are three types of presentations: Glossary Terms, Math Lessons and Solved Math Problems. I have made six curricula available: Arithmetic, Basic Algebra, Geometry, Advanced Algebra, Trigonometry and Calculus, all with one consistent voice at the affordable price of $15/month.
