Show that subtraction and division are not binaryoperations on `N`. – InterviewSolution

1.	Show that subtraction and division are not binaryoperations on `N`.
Answer» Let a, b `in` N For subtraction , `a,b in N implies a-b notin N, ` for a=3 and b=5 `:.` Subtraction is not a binary operations on N. For division , `a,b in N implies(a)/(b) notin N`, for a=2 and b=3 `:.` Division is not a binary operation on N. Hence Proved.
