| Description: Closure law for multiplication of complex numbers. 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-mulcl 8005 be used later. Instead, in most cases use mulcl 8034. (Contributed by NM, 10-Aug-1995.) (New usage is discouraged.) |
