- 1. Algebraic or symbolic computation is a branch of mathematics that deals with mathematical expressions and equations in symbolic form, rather than numerical form. It involves manipulating these expressions using rules of algebra to simplify, solve, or manipulate equations symbolically. This approach allows for the manipulation of variables and constants without needing specific numerical values, making it particularly useful in solving complex mathematical problems, computer algebra systems, and various scientific applications.
