What is Mathematics?
Mathematics is a broad and diverse subject which is used to model, analyse and understand several applications in the physical and biological sciences, engineering, management science, economics and finance. Its numerous applications are naturally interwoven with the underlying theory which is essential in developing one’s logical reasoning, quantitative skills and problem-solving techniques.

Mathematics: The course for you?
Mathematics is an excellent choice for anyone hoping to meet the demand for mathematics graduates in the job market, which values numeracy, ability in abstract reasoning and the skill to turn ideas into methods. If you have a natural ability in mathematics and are genuinely interested in applying mathematical solutions to problem solving, then this course will suit you well. It is also a great start for a career in actuarial work, finance or accounting, although these will require further training. The course has been successful over a long period in providing diverse career opportunities for many students.
Mathematics at Trinity
Trinity is justly proud of its long tradition of excellence in mathematics. Research interest in the School of Mathematics is enormously varied; ranging from the abstract ideas of modern algebra and analysis to practical ideas of numerical analysis, modelling and computer algorithms; the nature of fundamental particles and general relativity; nonlinear systems and fluid mechanics. This departmental diversity is reflected in the specialist degree-level courses available to students. With an academic staff that brings expertise and experience from many parts of the world, the course aims to be world class, with options for study and research in a wide range of mathematical areas.
The pathways available are Single Honours, Major with Minor and Joint Honours. There may also be an opportunity to take this subject up as a New Minor Subject from second year.
Graduate skills and career opportunities
A Degree in mathematics opens up the possibility of a career in a variety of industries and sectors. Graduates have found employment in computing, where mathematics skills have immediate and practical application. The financial services and internet security sectors are also common first destinations for graduates. Other options include statistics, teaching, accountancy, actuarial work, finance, and all areas of pure and applied mathematics. Many of these involve further study or intensive research in leading universities, including Cambridge, Oxford, and Imperial College London.
Your degree and what you’ll study
The programme is designed to provide a broad mathematical training that will allow you to work in any environment that requires strong numerical and logical skills. The modules offered can be grouped into four areas:
- Pure mathematics which explores fundamental concepts and abstract theories.
- Applied and computational mathematics which deals with practical problems.
- The mathematics of theoretical physics.
- Statistical models and methodology.
First and second years
Students take common modules in order to develop their skills and overall background in calculus, linear and abstract algebra, and other related subjects. Although most of the first and second year modules are compulsory, students are also able to choose a few approved modules in areas such as probability, statistics and theoretical physics (as well as Trinity Electives during the second year).
Third and fourth years
Students choose their own modules and thus specialise in the areas they find most interesting and appealing. There is a broad selection of modules in pure mathematics, theoretical physics, statistics and computer science (as well as Trinity Electives during the third year).

Students may choose to spend their third year to study abroad at one of our partner universities as part of an exchange programme. In particular, some of our students have recently completed their third year of studies at the University of Durham (UK), Université Lille 1 (France), the University of California at Berkeley (USA), McGill University (Canada) and the University of Melbourne (Australia).

The Mathematics degree in Trinity truly broadened my mathematical horizons. With such a broad range of topics available, and such positive student-staff interaction, I was inspired to pursue a Ph.D. in Oxford. However, academia was not my only option: many of my peers pursued careers in finance, computing and industry. The courses are well designed, and the staff are engaging and dedicated to helping students. Having so many courses to choose from allows you to tailor the degree to your interests perfectly. While the work can be hard, it is extremely rewarding and so I would highly recommend maths as an option to those with an interest.
The programme at Trinity has given me a passionate and well-rounded education in mathematics. It has given me the chance to study many different areas of Maths, as well as the possibility to study abroad in Australia and spend time working on research projects in the US. The opportunities and the high level of support have made me wish to continue my career in maths, and pursue a Ph.D. at the University of Minnesota.
The Maths degree at Trinity allowed me to explore a wide range of topics, and the research programmes for undergraduates guided my decision to pursue a Ph.D. at the University of Bath. I also worked in finance during summers and after graduating, the possibilities open to me have been incredibly broad. The course had great social aspects: I have made friends for life through the Mathematical Society and was a founding member of the 'Ireland for CERN' campaign – an experience not available elsewhere. The standard of courses, the opportunities, and the level of support and engagement of academic staff make choosing the degree a fantastic decision.
