Summary: Made me wish I was Einstein.
Review: Not much I can say about this book... It's full of VVVery difficult number puzzles... at least for me. Okay, so I don't get 'A's for my grades at school, but I think that even you might find it a little difficult. The way I see it, you will need lots of paper, patience and time, say 30 minutes or so to solve even the easiest of these. Why? Because basically, you are asked how many combinations can be formed from such and such. Example: How many ways get 31241 by adding prime numbers only? This is not really what the problems are like in the book, they are far more complicated than that. For me, it's just too much. I can't even do 1 single problem. I can't even look up the answers because uses some sort of a legend that I can't understand. But if you have an above average intelligence or are mathematically gifted, you will probably find some obscure short cut to the problem a la Gauss. For the rest, forget it. Word of warning: these are purely number problems. I can't tell if logic will help or even plays a part in this book, but the problems are NUMBER problems.
