Edit 0: Okay, so the Hamburger is the Integers Mod 2.
Edit 1: I can't be certain, but my guess is that ๐ญ is the nth power set of the reals. However, I'm unfamiliar with a topic that naturally contains both Z mod N and a power set of the reals, so I suspect my guess is wrong. Furthermore, I don't know what n could be referring to, other than an arbitrary integer.
Edit 2: The next line has a notation that I'm unfamiliar with, but my guess is that it has to do with Cartesian algebra. I don't know Cartesian algebra, and I'm not even confident I'm remembering the name correctly. I may look into this more later.
Edit 3: Okay, so the final line suggests the line referenced in Edit 2 describes a structure that's comparable to a polynomial ring on the integers Mod 2. Polynomial rings are relatively simple objects that (although most people don't realize it) people often start studying in middle school. Essentially, we're looking at something that behaves like algebra of objects like "2x+1" and "3x+2y+xy+0". I think the main question we should be asking is how many variables this ring has. Given the cardinality of an arbitrary power set of the reals, my assumption is that it's somehow similar to a polynomial ring with some uncountable number of variables. I cannot be certain however.
