Mathematics with Computer Science

Heriot-Watt University


Edinburgh Campus


Fundamental ideas in pure and applied mathematics are developed together with key concepts in computer science. In addition to expertise in both subjects, the course fosters the intellectual skills of analytical reasoning, systematic problem solving and the development and clear communication of ideas. Students studying Mathematics with Computer Science study roughly 75% mathematics and 25% computer science.

Year 1: The mathematics content is identical to that of the BSc in Mathematics. Two courses in software development in computer science introduce key ideas in programming.

Year 2: Work in mathematics extends in both applied and pure mathematics. In computer science, software design and programming languages are core courses.

Year 3: Topics develop mathematical skills and knowledge, and introduce ideas used at the forefront of modern mathematics. The computer science material includes theory of computing and programming language semantics.

Year 4: Further exploration and specialisation in advanced mathematics is possible with options related to our research expertise, together with computer science options in rigorous methods for software engineering and artificial intelligence and intelligent agents. Students will complete a mathematical project.
