# NUMBERS AND SETS - 2018/9

Module code: MAT2051

Module Overview

This module introduces students to some aspects of number theory, combinatorics and set theory. It complements other pure mathematics modules by considering a variety of topics not encountered elsewhere.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their ability to

• construct and interpret mathematical arguments in the context of this module;

• display subject knowledge by recalling key definitions and results;

• apply the techniques learnt to both routine and unfamiliar problems.

Thus, the summative assessment for this module consists of:

• One two-hour examination at the end of Semester 2, worth 80% of the module mark.

• One class test, worth 20% of the module mark.

Formative assessment and feedback

Students receive written comments on their marked coursework assignments.  Verbal feedback is provided in lectures and office hours.

Module aims

• provide an insight into classical number theory and its applications, and to some elementary combinatorics
• introduce axiomatic set theory and investigate properties of infinite sets
• establish a basis for further study in pure mathematics and logic

Independent Study Hours: 117

Lecture Hours: 33

Methods of Teaching / Learning

The learning and teaching strategy is designed to provide:

• Knowledge of the theory and practice of the topics covered.

• Experience of the methods used to interpret, understand and solve problems in these areas.

The learning and teaching methods include:

• Three 50-minute lectures per week for eleven weeks, some being used as problem classes.

• Online notes supplemented by additional examples in lectures.

• Two unassessed coursework assignments, marked and returned.

• Personal assistance given to individuals and small groups in office hours.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
