Theorem: the sum of any two even integers equals 4k for some integer k. "proof: suppose m and n are any two even integers. by definition of even, m = 2k for some integer k and n = 2k for some integer k. by substitution, m + n = 2k + 2k = 4k. this is what was to be shown." what's the mistakes in this proof?
