# Different Styles of Magic Squares of Order 16 Using Bordered Magic Rectangles and the Formula (a+b)^2

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

1. 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.
2. 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 16. For orders 8, 10, 12 and 14 see the links below:

Below are 153 Examples of Magic Squares of order 16. These are written in four parts:

• Part 1: Magic Squares of Order 16: Traditional and Bordered Magic Rectangles.
• Part 2: Magic Squares of Order 16: (A+B)2-Type: A=10, B=6.
• Part 3: Magic Squares of Order 16: (A+B)2-Type: A=12, B=4, where A as Two Blocks of Magic Rectangles of Order 4×6.
• Part 4: Magic Squares of Order 16: (A+B)2-Type: A=12, B=4, where A as Magic Rectangles of Order 4×12 or Magic Squares of Oder 4.
