Teacher of mathematics in preparatory classes for engineering schools, center of Salé, Morocco.
I just discovered this site and I see an excellent way to:
Improve my knowledge.
Find sources which are used to make exercises for my students.
Meet famous professors and students from various countries of the world.
Help by giving answers or comments when I can.
I note that my mother tongue is Arabic, so if I speak bad English, all corrections of my mistakes will make me happy.
