I have done this for years without knowing that there’s a name. Having the visual should make it a lot easier to explain to others. I do it on the opposite hands, but otherwise it’s basically the same. I guess it’s pretty much common sense, but I had a devil of a time showing others how to use it.

Pretty interesting. I’ve seen counting with using your fingers as binary digits before, which will let you count up to 512, but this being usable for math is really cool.

I like this, it’s so logical it seems obvious but I’ve never counted this way. Being able to count up to 100 and easily do basic arithmetic is great while being easier to manage than trying to calculate binary on my fingers (for me). Im gonna start using it.
