  • Calculus of relations, manipulation of binary relations with the algebra of sets, composition of relations, and transpose relations
  • Epsilon calculus, a logical language which replaces quantifiers with the epsilon operator
  • Fitch-style calculus, a method for constructing formal proofs used in first-order logic
