The study of logic is the study of the principles and methods used in distinguishing valid argu-
ments from those that are not valid.
The aim of this chapter is to help the student to understand the principles and methods used
in each step of a proof. The starting point in logic is the term statement (or proposition) which is
used in a technical sense. We introduce a minimal amount of mathematical logic which lie behind
the concept of proof.
