The first part of the module introduces the mathematics of sets in a non-axiomatic way, covering what is commonly referred to as naïve set theory. The versatility of using sets to define other mathematical objects is illustrated by studying functions and relations as sets. Further, the notions of countable and uncountable sets are explored.
Understanding and producing different types of mathematical proofs is an important part of the module. Besides standard techniques (direct proofs, proofs by contradiction, etc.) mathematical induction is introduced and studied as a powerful technique for proving statements about natural numbers.
The last part of the module introduces the basic ideas in propositional logic. This includes the use of truth tables, the laws of propositional logic, as well as the notion of a logical argument.
The aims of this module are:
- To provide a general understanding of sets and their connection to counting and defining other mathematical objects (including relations), mathematical proofs (especially inductive arguments), and the main ideas in propositional logic.
By the end of the module, students will be expected to:
- Have a basic knowledge of sets and the operations defined on them;
- Have a basic knowledge of binary relations and be able to check that a given relation is a partial order or an equivalence relation;
- Be able to compare the cardinalities of different sets using functions;
- Have a basic understanding of countable and uncountable sets;
- Be able to use mathematical induction and strong mathematical induction;
- Have a basic understanding of propositional logic and be able to use truth tables for checking the validity of a logical argument.
For students outside of the Department, an appropriate A level in Mathematics (or equivalent) is required for this module. If you are unsure whether you meet this criteria please contact maths@essex.ac.uk before attempting to enrol.

Teaching in the School will be delivered using a range of face to face lectures, classes, and lab sessions as appropriate for each module. Modules may also include online only sessions where it is advantageous, for example for pedagogical reasons, to do so.
The above list is indicative of the essential reading for the course.
The library makes provision for all reading list items, with digital provision where possible, and these resources are shared between students.
Further reading can be obtained from this module's

Exam format definitions
- Remote, open book: Your exam will take place remotely via an online learning platform. You may refer to any physical or electronic materials during the exam.
- In-person, open book: Your exam will take place on campus under invigilation. You may refer to any physical materials such as paper study notes or a textbook during the exam. Electronic devices may not be used in the exam.
- In-person, open book (restricted): The exam will take place on campus under invigilation. You may refer only to specific physical materials such as a named textbook during the exam. Permitted materials will be specified by your department. Electronic devices may not be used in the exam.
- In-person, closed book: The exam will take place on campus under invigilation. You may not refer to any physical materials or electronic devices during the exam. There may be times when a paper dictionary,
for example, may be permitted in an otherwise closed book exam. Any exceptions will be specified by your department.
Your department will provide further guidance before your exams.

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. Exceptionally it can
be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements,
industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist
of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules.
The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
