WebThe sum of integers in each row / column / major diagonal of a Magic Square of order N is 2N (N 2 +1) Add all the numbers in the square. It's the sum from 1 to n2, which is n2(n2 + 1)/2. This is equal to the sum of n rows, so each row is n(n2 +1)/2. In mathematics, proof by contrapositive, or proof by contraposition, is a rule of inference used in proofs, where one infers a conditional statement from its contrapositive. In other words, the conclusion "if A, then B" is inferred by constructing a proof of the claim "if not B, then not A" instead. … See more In logic, the contrapositive of a conditional statement is formed by negating both terms and reversing the direction of inference.
