The document discusses computer applications in mathematics. It provides examples of different types of computer algebra systems (CAS), including Maple, MATLAB, and Mathematica. Maple is a general purpose CAS developed in 1981. MATLAB is a numerical computing environment invented in the 1970s, mainly used for linear algebra and numerical analysis. Mathematica is a powerful programming language and CAS written by Stephen Wolfram in 1988 that uses a kernel architecture. In conclusion, computer science and mathematics have influenced each other, and computational mathematics has successfully combined the two fields.
