Easy -1.2 This is a straightforward proof requiring only the definition of even/odd numbers and basic case analysis (either one integer is even, making the product even). It's simpler than average A-level questions as it involves minimal algebraic manipulation and the logic is direct, making it easier than typical C3 content.
Product of two numbers, one of which is even is always even.
