I was bad at math, even very bad. My problem, I absolutely wanted to find x, draw an integral in 3D and dive into a vector space. But how to do it ? Mathematics otherwise. After 4 years of giving private lessons, I begin to grasp the redundant difficulties in the different pupils and students and that I once had, visualization. Of course ! Math is like art, physics, sand, you have to visualize, represent yourself. What is an equation? Or what does a vector space look like? Is an integral really a snake? Boole's algebra? Funny name ... So my method is that; teach you to appropriate key mathematical concepts by concrete, precise examples that you can appropriate and personalize. In this course, depending on your level of study, you will strengthen your calculation skills, learn to represent the fundamental concepts of mathematics in order to pave the way for a good progression.
