Theorem axaddf 8066

Description: Addition is an operation on the complex numbers. This theorem can be used as an alternate axiom for complex numbers in place of the less specific axaddcl 8062. This construction-dependent theorem should not be referenced directly; instead, use ax-addf 8132. (Contributed by NM, 8-Feb-2005.) (New usage is discouraged.)

Assertion
