Creative Magic Squares: Single Letter Representations

This paper brings magic squares of orders 3 to 10 in terms of single letter. In case of orders 8 and 9 there are two possibilities, i.e, one as normal magic square and another as bimagic square. In this situation, the magic squares are written in both the possibilities. In case of order 10, again there are also two possibilities. One without any blocks, and second as blocks of order 8, divided again in four blocks of order 4, known as block-bordered magic squares. Writing in terms of single digit "a", where  a can be 1, 2,..., 9. For the orders 3 to 9, few exercises are also written.
