Student A tries to define a function g: Q Z by the rule g m n = m n,for all integers m
Chapter 7, Problem 33(choose chapter or problem)
Student A tries to define a function g: \(\mathbf{Q} \rightarrow \mathbf{Z}\) by the rule
\(g\left(\frac{m}{n}\right)=m-n\), for all integers m and n with \(n \neq 0\).
Student B claims that g is not well defined. Justify student B’s claim.
