Calling out the transitivity property just distracts from the main point here (and anyway, it is also using the symmetric property). I removed the reference, which did not contain this explanation anyway. We don't need to define fallacy here, since there's a wikilink for those who need it.
- 17:0017:00, 6 January 2024 diff hist −298 Division by zero →Calculus: The calculation of the limit was simplified. Also, I think it is the expression 0/0 that is the indeterminate form, not the limit.

- 02:4402:44, 18 October 2023 diff hist −20 Group (mathematics) Although one does not change the concept of group if one requires it to be nonempty, it is cleaner not to add this condition, and I believe that most sources do not include this condition. With the condition there, every time one wants to check that a set with an operation is a group, one needs to check separately that it is nonempty.
