Take A Look At A Good Book is the third book in a series. The popular features of the two earlier books, Have Some Sums to Solve and At Last!! Encoded Totals, Second Addition, have been retained in Take A Look At A Good Book. The thirty-eight puzzles presented in Section 1, along with the cover, dedication, and preface puzzles, all fall into the special subcategory of additive alphametics. Each of their sums has a unique decoding, sometimes insured by the imposition of an initial condition.
Within the subcategory, two varieties of alphametics are include— the ideal, doubly-true type (abbreviated "i.d.t.") and the narrative type. In the former, all ten digits appear in the solution and a mathematically correct addition example results when the problem is read aloud. Directed approaches to each of the puzzles are offered in Section 2. These strategic outlines enable the solver to skirt around pitfalls and obstacles without removing the challenge associated with the quest for the actual answer.
In Section 3, solutions to all puzzles are given. The order of presentation of these solutions is intentionally different from that of the puzzles. This section also contains responses to all queries raised within the context of the narrative alphametics.
The major difference between this and the two earlier works is the prevalence here of "wider" i.d.t.s, wherein the sums span nine or more columns.
