**OBJECTIVES:**

• To introduce the basic notions of groups, rings, fields which will then be used to solve related problems.

• To examine the key questions in the Theory of Numbers.

• To give an integrated approach to number theory and abstract algebra, and provide a firm basis for further reading and study in the subject.
