Maybe this is a neurodiversity thing but for me going backwards to calculate something like a factorial recursively is hard to think about. It's exactly the same as if someone was trying to teach something about structural integrity in architecture and they said "OK you want to build a staircase. Imagine you're hovering in the air and you start to build stairs down..." I can't concentrate on whatever point they're trying to make with the example because I can't really get over the fact that it's easier to build from the bottom and not hover in the air in the first place.

Maybe try to imagine it from the architects point of view first, instead of from the brick layers? Like in an isometric drawing, for instance?
