| What was tried to be proven in this proof? Proof. Suppose m is an even integer and is an odd integer. By definition 2g for some integer q and by definition of odd, n= 2r+1 for some in- 4qr+2q = 2(2qr +q). Now 2qr+q is an integer 2-(some integer). %3D of even, m = teger n. Thus mn= because products and sums of integers are integers. Hence mn= and so, by definition of even, mn is even. (2g)(2r+1)
