For the first time in this work, two new concepts in construction of magic square are considered:

Using small blocks of magic or bordered magic rectangles. It is not always possible to write bordered magic rectangles for the non-sequential entries. In this case, the simple magic rectangles are considered.

Using algebraic formula (a+b)^{2}.

The whole work contains magic squares of even orders starting from order 8. This part is only for order 8 and 10. For orders 12, 14 and 16 see the links below:
