User:Trovatore/Arithmetic and exponentiation in various numerical structures
Many times, usually in the context of discussions about the expression , I have wanted to express certain ideas that I think are relevant, but it would be too long-winded inline, and also I didn't want to spend the time. So I'm hoping that pointers to this essay may prove useful.

For most purposes this is true.
