How do you place numbers in a 3 by 3 square to get 15 in each row?

To create a 3 by 3 square that sums to 15 in each row, column, and diagonal, you can use a magic square. Place the numbers 1 through 9 in the following arrangement:

<code>8  1  6
3  5  7 4  9  2
</code>

Each row, column, and diagonal in this configuration sums to 15.
