Problem II.5 We would like to prove the following statement by contraposi- tion, For all natural numbers x and y, if x + y is odd, then x is odd or y is odd. 1. Translate the statement into a statement of predicate logic. 2. Provide the assumption required for a proof by contraposition for the given statement. 3. Provide the conclusion for a proof by contraposition for the given state- ment. 4. Prove the statement is true by contraposition Problem II.5 We would like to prove the following statement by contraposi- tion, For all natural numbers x and y, if x + y is odd, then x is odd or y is odd. 1.
