Additive Number Theory: Inverse Problems and the Geometry of Sumsets
Many classical problems in additive number theory are direct problems, in which one starts with a set A of natural numbers and an integer H -> 2, and tries to describe the structure of the sumset hA consisting of all sums of h elements of A. By contrast, in an inverse problem, one starts with a sumset hA, and attempts to describe the structure of the underlying set A.

These book sets are top picks for elementary-level libraries and these new releases are especially recommended as staples for any serious collection, promising lasting reference and relevance. Renee C. Rebman's CATS joins others in the 'Animals Animals' series, offering just under 50 pages of detail about cats. From a history of cat and human involvement to behaviors and life cycles, CATS pairs fine color photos with excellent analysis.
