This is nothing new from Gail Howard, or at all. These wheeling systems can be worked out mathematically, without paying for this book. There are also lots of websites that offer number generators and wheeling system explanations for free. If you want it all spelled out for you then buy this book, but if you are willing to do a little mathematical work check out lottery information website like [...].

Ex Output:
Negative


Ex Input:
I love this dish. I try to keep from microwaving my baby's food, so I put really hot water in the base of this bowl. It warms my baby's food (even food from the fridge) and keeps it warm. As another reviewer said, the dish is very difficult to separate.

Ex Output:

Positive
