Question

prove the commutative property of addition and multiplication​

Answer 1

Answer:

If y> 1 then y=s(z) for some z (this is easy to prove by induction) and x+y=s(x+z). One can prove inductively that addition, thus defined, is commutative, and this proof naturally appears well before a proof that multiplication is commutative.
