Hello!
I have been a Khan Academy user since 2018. I found this site when I was looking for an explanation of the Pytagorean theorem. What I really like about Khan Academy (in math, history, science....) is that they always explain why a historical event occurs, why a theorem works, why a physical phenomenon occurs ..etc..
With the Khan academy, I started coding, I was finally able to study many math subjects that I wanted to discover and many other things.
It is a fabulous site and many thanks to it!
