Definition: even number is of form n × 2 for some integer n (where "×" is multiply symbol)
Definition: odd number is of form m×2 + 1 for some integer m.
Clearly an odd number is not even
Odd times even
(m×2 + 1) × n×2 = m×2×n + n×2 = (m×n +n) × 2
Note (m×n + n) qualifies as ‘some integer’, so the result is always even
Because the result is even, it cannot be odd.
