An addition-multiplication magic square of order \(n\) is an \(n\times n\) matrix whose entries are \(n^2\) distinct positive integers such that not only the sum but also the product of the entries on each row, column, main diagonal and back diagonal is constant. Four conjugate addition-multiplication magic squares of order 9 are constructed. This implies that there exists an addition-multiplication magic square of order 18.
