Commutative Ring: Let R be a set of elements a,b,c .... for which the sum (a + b) and the product (ab) of any two elements a and b of R are defined is called a commutative ring(adsbygoogle = window.adsbygoogle || []).push({});

This is my understanding, tell me if I am wrong....

f(x) = 1/x

Domain of f: { x | x =/ 0 } = A

Thus any two integers (a + b) = 0 and (ab) = 0 are not in the commutative ring..... commutative ring being A

Is this correct?
