Thank for your math classes

Hello, Khan Team :)

I am really happy to thank all of you for your work and effort put in this roject. This is awesome. I study highschool maths by your videoclasses. They are clear as blue heaven. Very transperent. It is quite magical how Sal explains so complex abstraсtions in such simple manner.

Very useful and insipiring to study further.

Big thank you from Russia :)
