Hints

CAS stands for computer algebra system, which is now integrated in some graphics computers. CAS computers can be used to solve computing tasks from the most diverse areas of mathematics, from calculating simple tasks to working with symbolic expressions such as variables, functions and matrices.

For example, a CAS computer can form derivation functions or the root function of an original function, and can also perform termforming or the conversion of equations. With these skills of a CAS calculator, students can understand and understand the complexity of mathematics with its different mathematical structures.
