Firstly, this product arrived at my house in the UK from bookcloseouts in Canada in only 12 days - very pleasing.The book itself looks promising, although perhaps aimed at a young audience; but also:My copy came wrapped-together with a beautiful miniature wooden abacus.I'm delighted.David Morton

I am pleased with this little book - gives good history and introduction. I have just started reading it and find it a good introduction and holds my interest. I recommend this to anyone who is interested in learning to use the Abacus.
