# NUMBERS AND SETS - 2020/1

Module code: MAT2051

In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.

These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.

Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.

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

Attributes Developed

**C** - Cognitive/analytical

**K** - Subject knowledge

**T** - Transferable skills

**P** - Professional/Practical skills

Overall student workload

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.
