Algebraic simplification

Definition

Algebraic simplification is the process of reducing an algebraic expression to its simplest form by combining like terms, removing unnecessary parentheses, and applying algebraic rules. This process is crucial as it helps make complex expressions more manageable and easier to analyze or compute. By simplifying expressions, we can also identify patterns that may lead to further insights in symbolic computation.
