Can the numbers 1-9 in 3x3 grid equal 12 with out using the same numbers?

Yes, it is possible to arrange the numbers 1-9 in a 3x3 grid such that each row, column, and diagonal sums to 12 without repeating any numbers. One example is to use the following arrangement:

<code>  8  1  3
4  5  3 0  6  6
</code>

However, it's important to note that achieving this strictly with the numbers 1-9 without using zeros or repeating numbers is not feasible while maintaining the requirement for all rows, columns, and diagonals to sum to 12.
