How to Use This Calculator
  1. Enter the logical expression using variables and connectives (AND, OR, NOT, XOR, IMPLIES).
  2. The calculator generates all 2^n input combinations for n variables.
  3. Review the truth table with the expression value at each row.
  4. Identify tautologies (always true), contradictions (always false), and contingencies.
  5. Use the truth table to verify logical equivalence or entailment between expressions.
