Logic

Propositional logic is the foundation of all mathematics. Every proof you'll ever write uses these building blocks: implication, conjunction, disjunction, negation, and the biconditional. Master these and you can prove anything.

  1. 01 True is true trivial
  2. 02 Implication and intro/apply easy
  3. 03 Conjunction (and) easy
  4. 04 Disjunction (or) easy
  5. 05 If and only if medium
  6. 06 Negation and contradiction medium
