I found this technique in Tim’s article and, when I tried wrapping my head around it, and creating variants of it, I had a hard time figuring out what was going on exactly. I did a lot of back-of-the-envelope calculations, and I thought it would be useful to share a mathematical explanation.
I’ll describe the technique, its limitations, and the math that make it work. But don’t worry about the math: it’s basically addition and multiplication, and I’ve broken down the steps as much as possible—also there will be nice graphs.
