TIMS Task

This can serve as a Problem of the Week.

One of the possible solutions:

Note: The square does not fit the classic definition of a magic square, but it is similar. All the rows and columns sum to 10, but the diagonals do not. See DPP item B.

D. Almost a Magic Square

Put the digits 1, 2, 3, and 4 in the boxes below so that the sum of every row and every column is 10. Use four 1s, four 2s, four 3s, and four 4s.

Hint: Instead of erasing, write four 1s, four 2s, four 3s, and four 4s on little slips of paper and move them around in the boxes until you find a solution.
