Preface How to Use This Book (*)

I'm still in the process of figuring out exactly what this is for.
  • Future lecture notes for the hopeful possibility that one day I am teaching a course over this material.
  • Current notes for students taking the first year algebra sequence.
  • Assistance in studying for the Algebra Qualifying Exam at UNL.
  • Clout.

Blocks.

  • Definition.
    These are pretty standard and probably what you'd be expecting. The building blocks of what we'll be working with.
  • Examples.
    Specific instances of a definition.
  • Theorem.
    A result.
  • Lemma.
    A more technical result used specifically in the proof of a larger result.
  • Corollary.
    An important result whose proof comes directly from a previous theorem.
  • Proposition.
    Results that require proof but are more specific and/or contained in a larger result coming later.
  • Exploration.
    Generalizations, specifics, smaller results, things are are less essential to the course or results who's proofs are usually skipped.
  • Problem.
    Used for qualifying exam problems.
  • Remark.
    Providing context in the form of foreshadowing or content not covered in this text. In general, there shouldn't be anything defined in a remark, they should be entirely optional.
  • Discussion.
    Usually for arguing about notation.
  • Context.
    Historical and etymogical origins.
  • Footnotes.
    Sometimes act like remarks. However, most are strictly for fun and add little to no educational value, at least in the traditional sense. 2 
It should really be “feetnote” if you think about it.
