How do you solve a 3x3 magic square with the sum of 12?

Answer 1

You can't do it with 9 different integers. Either you repeat integers or you use fractions.

Repeating integers gives the trivial solution 4-4-4; 4-4-4; 4-4-4 so we head into fraction country.

Top row: 1.6 - 7.2 - 3.2; middle row: 5.6 - 4 - 2.4; bottom row: 4.8 - 0.8 - 6.4

Answer 2
