Holder of a master's degree in Mathematics and Computer Science, I naturally turned to teaching for several reasons: contact with students among others. On the other hand, I realized that students only retained the main part of the lesson, that is to say the formula. And the whole demonstration went over their heads....
I also have experience with children suffering from dyscalculia or other.
Also a facilitator of remedial courses during school holidays on the ORA platform.
Therefore, the best way for the student to succeed in mathematics and learn a formula is to practice as much as possible. That's why 99% of my course is made up of exercises.
