Maybe learn some algebra before you start being pedantic. You can't divide by zero and any notation that does is shorthand for something else. There is no way to define 6/0 in the same way as 6/3 and the fact that you need a whole-ass metric space so you can have convergent sequences shows that.

And n^0^ is not just arbitrary but the definition of an empty sequence of an operation is that it yields the neutral element. The empty sum yields 0, the empty product yields 1 and n^0^, in the most naive and direct interpretation, Is n multiplied by itself no times, hence an empty product and therefore yields 1 (there is a caveat for 0^0^ but that's like a whole lecture). Sure that is arbitrary in the sense that any axiomatic system is arbitrary but not in the /0 sense where it keeps changing based on context and no self-consistent axiomatic system is possible where /0 is assigned a value.

Hexbear Proposals chapo.chat matrix room.

This will be a place for site proposals and discussion before implementation on the site.
Every proposal will also be mirrored into a pinned post on the hexbear community.

Any other ideas for helping to integrate the two spaces are welcome to be commented here or messaged to me directly.

Within Hexbear Proposals you can see the history of all site proposals and react to them, indicating a vote for or against a proposal.

Sending messages will be restricted to verified and active hexbear accounts older than 1 month with their matrix id in their hexbear user profile.

All top level messages within the channel must be a Proposals (idea for changing the site), Feedback (regarding non-technical aspects of the site, for technical please use https://hexbear.net/c/feedback), or Appeals (regarding admin/moderator actions).

Discussion regarding these will be within nested threads under the post.

To gain matrix verification, all you need to do is navigate to my hexbear userprofile and click the send a secure private message including your hexbear username.
