Consider the logical argument below involving arbitrary real numbers a and b. If a 0 and ab =0 then b = 0. However, b 0. Therefore if a 0, then ab 0. It is given that p: a = 0; q: b = 0; r: ab = 0. Translate the argument into symbolic logic using the symbols defined above. Test the argument for validity.
