This work brings magic squares of orders 3 to 10 in terms of **single letter** ** “a”**, where

**can take any value from 1 to 9. The magic squares of orders 8 and 9 are written in two ways, i.e, one as**

*a***normal magic squares**and another as

**bimagic squares**. In case of order 10, we have written it in three different ways. One as normal way, the second as block of order 8, divided again in four blocks of order 4. The third is with inner block of order 8 as bimagic square.

Before we write examples of magic squares, below is an idea of single letter representations of numbers:
