Description: Show the commutative law for an operation on a toy structure class of commuatitive operations on . This illustrates how a structure class can be partially specialized. In practice, we would ordinarily define a new constant such as "CAbel" in place of . (Contributed by NM, 17-Mar-2013.) (Proof modification is discouraged.) |
