 11 Algebra
 **********
 
 This section covers the Calc features that help you work with algebraic
 formulas.  First, the general sub-formula selection mechanism is
 described; this works in conjunction with any Calc commands.  Then,
 commands for specific algebraic operations are described.  Finally, the
 flexible “rewrite rule” mechanism is discussed.
 
    The algebraic commands use the ‘a’ key prefix; selection commands use
 the ‘j’ (for “just a letter that wasn’t used for anything else”) prefix.
 
    Editing Stack Entries, to see how to manipulate formulas
 using regular Emacs editing commands.
 
    When doing algebraic work, you may find several of the Calculator’s
 modes to be helpful, including Algebraic Simplification mode (‘m A’) or
 No-Simplification mode (‘m O’), Algebraic entry mode (‘m a’), Fraction
 mode (‘m f’), and Symbolic mode (‘m s’).  Mode Settings, for
 discussions of these modes.  You may also wish to select Big display
 mode (‘d B’).  Normal Language Modes.
