This problem could probably be explained a little better.

This is pretty simple given that there is a built in function to build magic squares. If not, the algorithm to "manually" build a magic square by filling a matrix is already well-known.

I use the sum(n) and it gives me 15 for all the rows or the columns. What is wrong with this, because it does not accept this answer. I also calculated the sum of the first row to get just 15 once, still it does not accept it.
