Question

the horizontal,vertical and diagonal columns and rows of a magic square all add to the same sum.use the digits 1-16 one time each to make a magic square

Answer 1

To construct a 4x4 magic square, list all the values, left to right, top-to-bottom.

Now, leaving the diagonals in place, reverse the order of the other numbers, going right-to-left, bottom-to-top.

Google magic squares.

Squares of odd order are easy to construct, following a simple set of rules. Even-order squares are more complicated, and the 4x4 rule does not apply to larger squares.
