Yes I did in fact read that but didn't take enough time to absorb how that extends to the algorithm he describes.

For example to calculate sqrt(1024) only requires adding 1+3+5 and later 61+63, rather than all odds from 1 to 63.

(1+3+5) * 100 = 900 = sum of odds to 60. Cool...

As I continue to investigate it starts to make sense .... so let me at it for a while and I'll be fine.

Thanks
