A computer algebra system (CAS) is a software program designed to perform symbolic mathematics. Unlike standard calculators that handle numerical calculations, a CAS can manipulate mathematical expressions in their symbolic form, allowing for operations like simplification, differentiation, and integration. This makes it a valuable tool for students, educators, and professionals in fields such as engineering, physics, and mathematics. CAS software can solve equations, factor polynomials, and even plot graphs, providing users with detailed solutions and visual representations. Popular examples of computer algebra systems include Mathematica, Maple, and SageMath. These tools enhance mathematical understanding and streamline complex calculations.
