Exercises Posed by Tarski

Abstract

This chapter contains translations and discussions of the fourteen exercises that Alfred Tarski published for enhancing instruction in Polish gimnazjums. The translations appear in boxes in each of the numbered sections that follow. They are meant to be as faithful as possible to the originals, and follow the conventions used for the longer translations in other chapters. In particular, all [square] brackets in the translations enclose editorial comments inserted for clarification. Each individual exercise is accompanied by a discussion by the present editors: the material outside the box. These discussions include contextual information, descriptions of responses from students, teachers, and other mathematicians, and full or partial solutions by the present editors. The paragraphs immediately following this one describe general aspects of all of the exercises.
