Computer Algebra System (CAS): A computer program designed to perform symbolic mathematical manipulations, such as solving equations, differentiating and integrating functions, and simplifying algebraic expressions.
Symbolic Computation: The manipulation of mathematical expressions and equations in their symbolic form, without numerical evaluation, allowing for more general and flexible problem-solving.
Numerical Computation: The use of numerical methods and algorithms to perform calculations and solve problems that involve numerical data, often with the aid of a computer.
