I request that this posted question be re-opened. It was closed as a duplicate, which it is. Unfortunately, the original question itself has been closed, and therefore, could be deleted at any time. I feel that this makes labeling the new question as a duplicate inappropriate, because the underlying reference is (in effect) broken.

C pure PSQ or contextless SV. OP states well-known standard def's then asks "is this correct?"
15:54
@BillDubuque Or one might say the well-known standard definition included is the context, and you misinterpreted the core question (which seems to be "I have this ring... can I also say it's actually an algebra?")

I'm willing to believe there's a duplicate out there, but I couldn't find it. Maybe https://math.stackexchange.com/questions/380177/what-is-the-difference-between-a-ring-and-an-algebra with some suitable comments?
