BSc Mathematics and Computer Science
About this course
Mathematics and computer science is a natural pairing because the two disciplines are deeply intertwined. Computer science draws heavily on discrete mathematics, logic, algorithms, and probability theory, while mathematics increasingly uses computation as a tool for exploration and proof. Studying both together develops a distinctive intellectual profile: the rigorous analytical thinking of mathematics combined with the algorithmic and systems-oriented thinking of computer science, each enriching and extending the other. At the University of Liverpool, this three-year programme gives you a solid grounding in both disciplines. In the mathematics strand, you will develop expertise in calculus, algebra, analysis, probability, and statistics, working with the precision and rigour that mathematical training demands. In the computer science strand, you will study algorithms and data structures, programming paradigms, software engineering, computer architecture, and computational theory. The two strands reinforce each other throughout the degree, and you will engage with topics that sit at the interface, such as computational mathematics, cryptography, and the mathematical analysis of algorithms. The programme includes a year abroad, giving you the opportunity to study at a partner institution and experience a different academic environment, broadening your perspective and your professional network. Graduates from this combined degree are in strong demand across technology, finance, and research. Software engineering, data science, machine learning, and algorithm development are natural career directions for those who want to work in industry. The financial sector, particularly in quantitative roles, values the mathematical depth that this degree develops alongside the computing capability. Research careers in theoretical computer science, applied mathematics, or at the intersection of the two fields draw those who continue to postgraduate study. The degree also prepares graduates well for roles in cybersecurity, where mathematical foundations are important, and in operations research, where mathematical modelling and computational techniques are applied to complex optimisation problems.
