Please could you check what is with the video. Some minutes are without the sound and in a very quick speed, I cannot see it clearly.

@tolgochka I'm sorry. That was an attempt to skip over some boring math, but it is a bad format for learning. Everything I wrote when the sound cut out should still be on the board after it goes back to regular speed. Try pausing the video after it goes back to regular speed. I apologize again for the bad format.

Thanks, this was great. But again, the sound cuts out at some points - is this intentional?
