Thank you for the kind words! I try to do my best to present the concepts as clearly as possible and I hope they are at least some bit understandable to somebody who doesn't really have a "math brain".
you're welcome.
I was able to follow the dividing part but then you lost me:)
did you, btw, make the graphs yourself?
Imagine, what a piano player could do with six fingers on each hand. LOL
Well, the part about division is the important part really ;)
Yep, I made the images, but I used existing CC0 and public domain graphics for some of them like the shot of the pizza (that I sliced awkwardly :P), the hand and the backgrounds.
