I am now reading Isabelle/HOL a proof assistant for higher order logic and at the same time learn to use Isar.

The method "arith" is a combination of decision procedures for
arithmetic. In its standard setup, it first tries Fourier-Motzkin
elimination (for naturals, integers, or reals; see  for an
overview), and if that fails, it tries a quantifier elimination
procedure for Presburger arithmetic (e.g., see ). More decision
procedures may also be added.
