Description: Multiplication of complex numbers is commutative. Axiom for real and complex numbers, derived from set theory. This construction-dependent theorem should not be referenced directly, nor should the proven axiom ax-mulcom 7689 be used later. Instead, use mulcom 7717. (Contributed by NM, 31-Aug-1995.) (New usage is discouraged.) |
