WebSome animals that are not dogs are loyal. discrete math. Write a negation for each statement. \forall n \in \mathbf { Z } ∀n ∈ Z. , if n is prime then n is odd or n=2. discrete math. Prove that for every integer n, n2 is even if and only if n is even. discrete math. Prove that the product of two even integers is even. Web26 de sept. de 2006 · Proof: Let n be an integer. We must show that n^2-n+3 is odd. Since n is an integer, then n^2-n+3 = n (n-1)+3, where n and n-1 are two consecutive integers. Then by the parity property, either n is even or n is odd. Hence the product of any even and odd number, n (n-1) must be even and n (n-1) + (Odd number) = odd number.
