Seriously, people! This book caught me off guard! I was amazed at how interested my neices were in the subject matter! I would have thought they would find it over their heads - but my neice STILL knows her binary sequence from 2 to 2048 (and it has been a long time since I read the book to her). I can see why it is so expensive to get one's own copy, but I think I will have to get it anyway!
Another great math reader! Explains binary numbers so well, that after reading it you will have one of those "Oh, why did I not think of that before?" moments. Or feel sad that you never really understood binary nymbers....
