All mathematical questions about computer science, including theoretical computer science, formal methods, verification, and artificial intelligence. For questions about Turing computability, please use the (computability) tag instead. For numerical analysis, use the (numerical-methods) tag. For questions from scientific computing, use (computational-mathematics).

Computer science is the study of the theory, experimentation, and engineering that form the basics for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale.

Some fields of computer science such as computational complexity theory (which explores the fundamental properties of computational and intractable problems) are highly abstract, while fields such as computer graphics emphasize real-world visual applications.
