Description: Addition of complex numbers is associative. This theorem transfers the associative laws for the real and imaginary signed real components of complex number pairs, to complex number addition itself. Axiom 9 of 22 for real and complex numbers, derived from ZF set theory. This construction-dependent theorem should not be referenced directly, nor should the proven axiom ax-addass 9578 be used later. Instead, use addass 9600. (Contributed by NM, 2-Sep-1995.) (New usage is discouraged.) |
