the image was really helpful for knowing what's going on here! can you also give a little description? it wasn't super clear to me just from the pic

also (this is a Socratic convention that I also use at Joyable!) when you're making branches, preface them with your initials so we know it's a branch you were working on

e.g. al_cube_root

once you do it once, it should keep that as the default then on
