1. Introduction to Mathematical Logic
Mathematical logic is a crucial field that addresses the science of reasoning and verification of statements. It encompasses propositional logic, which serves as the foundation for various logical operators such as conjunction, disjunction, and negation. The study of logical implications and their interpretations is vital in numerous applications including program verification and artificial intelligence.

What we have learnt
- Mathematical logic helps in determining the truth or falsehood of mathematical statements.
- Propositional logic consists of declarative statements that can be classified as true or false, and various logical operators can be utilized to combine these statements.
- There are distinct logical operators used within mathematical logic, including AND (conjunction), OR (disjunction), and implications, each with its unique applications and truth tables.
Key Concepts
- -- Proposition
- A declarative statement that can be either true or false, but not both simultaneously.
- -- Logical Operators
- Symbols like OR, AND, and NOT that perform operations on propositions to yield a resulting truth value.
- -- Implication
- A conditional statement that describes the relationship where one proposition (p) leads to another (q), symbolized as p → q.
- -- Truth Table
- A table that lists all possible truth values for a set of propositions and the corresponding result of the logical operations.
