Symbolic representation

Definition

Symbolic representation is the use of symbols to represent logical expressions and relationships in algebraic logic. It allows for the formalization of logical arguments and the manipulation of these expressions using algebraic techniques, making it easier to analyze complex logical structures. This concept has played a crucial role in the historical development of algebraic logic, bridging the gap between language and mathematical notation.
