This lecture explains Disjunctive Normal Form (DNF), an important normal form in propositional logic that is frequently asked in Discrete Structure university exams, especially in logic simplification and conversion questions.

✅ You Will Learn (Exam-Oriented):

What is a Normal Form
Meaning of Disjunctive Normal Form (DNF)
Structure of DNF (OR of AND terms)
Difference between DNF and general logical expressions
Step-by-step method to convert expressions into DNF
Use of logical laws in DNF conversion
Solved exam-oriented examples
How to write DNF answers in proper exam format

The explanation is stepwise, law-based, and strictly exam-focused, ideal for 5-mark & 10-mark questions and viva.
