We can think that a particular theorem of algebra is provable from the
axioms of set theory (via definitions of the appropriate algebraic notions)
without thinking that we would ever have discovered that algebraic theorem
-- that is, without thinking that we would ever have thought of looking at
these particular sets in this particular way -- without thinking
'algebraically'.  That's what I mean when I deny that the methods of algebra
are the methods of set theory.
