Formal systems are structured frameworks used in mathematics, logic, computer science, and other fields to rigorously define and manipulate symbols and statements according to a set of rules. Here are the main components of a formal system: 1. **Alphabet**: This consists of a finite set of symbols used to construct expressions or statements in the system. 2. **Syntax**: Syntax defines the rules for constructing valid expressions or statements from the symbols in the alphabet.
