What is De Morgan's theorem used for?
De Morgan's theorems convert AND-form expressions to OR-form and vice versa — essential for implementing logic with NAND or NOR gates only. They are widely applied in digital electronics and discrete math simplification problems.
What is the difference between Boolean algebra and regular algebra?
In Boolean algebra, variables are binary (0 or 1) and operations are AND, OR, NOT — not arithmetic.
- A + A = A in Boolean vs 2A in regular
- A AND A = A in Boolean vs A squared in regular
- Complement has no regular algebra equivalent
How do you prove Boolean identities?
Use truth tables to verify all input combinations, or apply algebraic laws step-by-step. For exams, algebraic proofs are preferred as they demonstrate understanding of the laws.
