When the red triangle was transferred at the top portion, it occupied a portion of its previous location (at the mid part of the hypotenuse). That is why when rearranged, there is one square unoccupied… It was reoccupied by the red triangle.

Take the 2nd odd number, 3. Since ’3′ is number ’2′ meaning 2nd, take the ’2′ and double/square it, leaving a 4. Put a space between the four and 3, then find the difference between 3 and 4. The difference will be the center number. Then divide by 100. 3_4 > 4-3=1 314 314/100=3.14
