Awesome, thank you for taking the time to explore it more, that makes sense to me

I’m curious, couldn’t we define z as only 1/0? Then 2/0 would have to be factored to 2*(1/0) first and it would solve this specific example of things breaking. I haven’t done advanced math in a while but your comment picked my curiosity haha

I remember 1/0 is pretty important in limits and stuff, it just seemed to me that this specific example seems not too hard to resolve
