| Description: The complex numbers are an Abelian group under addition. This version of cnaddabl 19844 shows the explicit structure "scaffold" we chose for the definition for Abelian groups. Note: This theorem has hard-coded structure indices for demonstration purposes. It is not intended for general use; use cnaddabl 19844 instead. (New usage is discouraged.)
