Definitions

1. Elementary algebra: A system for representing and manipulating unknown quantities (variables) in equations.
   uncountable
2. Abstract algebra: A broad field of study in modern mathematics (often mentioned alongside analysis) loosely characterized by its concern for abstraction and symmetry, dealing with the behavior, classification, and application of a large class of objects (called algebraic structures) and the maps between them (called, most generally, morphisms).
   capitalized, sometimes, uncountable
3. Any of several objects of study in Algebra
   countable, uncountable
4. A universal algebra.

6. A collection of subsets of a given set, such that this collection contains the empty set, and the collection is closed under unions and complements (and thereby also under intersections and differences).
