I must apologize for the error on my recent post. The second challenge is not possible with the 4 in a corner. Please see the amended challenge below. Well done to all those who persevered to try to find a solution to an impossible problem.
Test your
perseverance: Complete this
magic square so that it has a magic number of 12. Fill in the squares using the numbers 0 to
8. It will require some trial and
improvement.

Helpful Hint: Draw the 3x3 grid. Then cut out little squares of paper with the
numbers on them so you can move them around on the grid to try different
possibilities until you find the solution.
