MATH.12:12 - Relations

  • B.5.RA recovers an argument’s premises and consequences. This pattern obtains the values and operations carried by its constructive steps.
  • MATH.4 constructs witnesses by induction; MATH.5 extends assignments through mathematical composition. Their results can supply operations used in the extracted construction.
  • MATH.2 governs independence from identified input descriptions; MATH.7 transports a construction through a bijection.
  • MATH.9 constructs a choice compatible with symmetry. Its existence and computation conditions remain relevant when the extracted result includes such a choice.
  • B.5.RR revises an affected argument; B.5.QD develops a missing construction into the next mathematical question.
  • C.29.1 supplies a needed result-transfer argument; C.29.2 develops a missing computational formulation; C.29.3 connects a computation with its execution and interpreted result.
