That one is also near the top of my reading list.
I finally set up my “math table”* tonight so I’m going to focus on that for now. (plus slowly working through the nand2tetris book and Algorithms 4th ed.)
(*The table is just for math, since I’m behind on my goals in that area and want to make sure my books don’t get buried by other things. I have another table next to it for my computer and other study topics.)
