@dpiponi@mathstodon.xyz Algebra is based on unknowns: e.g. x being a variable instead of writing 3. These examples are what happens when multiplication operator is an "unknown", and when a bilinear function is an unknown. They're just more complex unknowns.

@sjb@mstdn.io Exactly right. But I think there's an interesting story here which is that when we write down something like 3x+5 that expression is itself a free construction and in a sense that's closer to what I'm talking about than the x itself.
