width of 9 the T-Total (t) is -45 smaller than the previous T-Total (t) (the origin) As when v = 32, t = 142 and with a translation vertically by -1 v = 23, t = 97, and 97 - 142 = -45, therefore the above statement it correct.

You notice you add 4 each time so that 4 is the multiplier, so you have 4 ??N which equals 4N. To get the +4 you subtract the difference of 4 from the original number of tiles you started with, 8.
