Of course these aren't particularly interesting without some additional constraints as to how the operations behave.  Some of the most important abstract algebrae are as follows:

* MathematicalGrouP''s''
* RinG''s'' and ModulE''s''
* FielD''s'' and VectorSpace''s''
* AssociativeAlgebra''e'' and LieAlgebra''e''
* LatticE''s''

A subalgebra of a given algebra is a SubSet thereof closed under all relevant operations, so that it forms an algebra of the same kind under them (or more technically their restrictions).  A MappinG between two algebrae that preserves all relevant operations and relations is called a HomoMorphism; if it is also a BiJection, it is called an IsoMorphism.  Isomorphic algebrae are indistinguishable as far as algebraic structure is concerned.
