the unique Factorization thorium for intcgcrs, Rational numbers, Irrational numbers --- Upper
bounds , Maximum Elements, least upper bound, the completeness axiom, some properties for
the sypremum, properties of the integers deduced from the completeness anxiom- The
Archimedian property of the real number system Rational numbers with finite decimal
representation of real numbers absolute values and the triangle inequality – the Cauchy-
Sohewarz,inequality-plus and minus infinity and the extended real number system.
Basic notions of asset theory. Notations –ordered pairs – Cartesian product of two sets,
Relations and functions further terminology concerning functions one one functions and inverse
composite functions- sequences-similar sets – countable and uncountable sets- uncountability of
the real number system-set algerbra-countable of collection of countable sets.
UNIT II
