| Description: Closure law for addition 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-addcl 8188 be used later. Instead, in most cases use addcl 8217. (Contributed by NM, 14-Jun-1995.) (New usage is discouraged.) |
