"Leonardo of Pisa's Liber Abaci (Book of Calculation) is one of the most
important books in the history of European mathematics. Leonardo learned
his mathematics from the Islamic mathematical tradition (some have even
argued that he should be considered part of that tradition), but he
wrote his books in Latin. As a result, he became one of the most
important mediators of that tradition to European readers ... here it is
at last, the Liber Abaci in English. It is now possible for
mathematicians who are interested in history to read it, and for
students to read portions of it in their history courses ...
[Leonardo] was a great mathematician, and here is an accessible and
readable edition of his most famous book. Don't miss the opportunity to
get a copy." -MAA Online
