Perelman I. and . Entertaining Algebra 6th Edition . 1955 [pdf 186sc 184c. 4. 23mb]Do not look at this book as an easy-to-understand algebra textbook for beginners. Like my other works of the same series, “Entertaining Algebra” is not primarily a textbook, but a book for free reading. The reader whom she has in mind must already have some knowledge of algebra, at least vaguely learned or half-forgotten. "Entertaining algebra" aims to clarify, resurrect and consolidate these scattered and fragile information, but mainly - to educate the reader's taste for algebra and to arouse the desire to independently fill in the gaps of their training in educational books. In this regard, the setting of "Entertaining Algebra" is the opposite of the problems of, for example, a book such as "Numbers and Figures" by Rademacher and Teplitz), which does not require the reader to "remember what we learned in mathematics in our young years" .. My book, by contrast, seeks to help anchor school knowledge and skills... From the foreword.
