Topic: Division monoids and wheels

I can't help seeing the parallel between docs#division_monoid and wheels. Are wheels useful for anything?

Violeta Hernández (May 23 2022 at 17:16):

You can define a wheel of fractions from any field (?) that behaves relatively nicely

But really 90% of the times I see wheels mentioned, some 13 year old kid is trying to divide by 0

Until you mentioned docs#division_monoid with your refactor, I had never heard of it "in maths". Wheels, I only found out now by following your link. Maybe they are useful, but I have certainly never used them!

Also, I use the projective line a lot and wheels have never showed up in what I do.
